Tucked along 4th Avenue East in Olympia, Washington, Eastside Big Tom has been flipping burgers and serving smiles since the late 1940s. As Washington’s oldest drive-thru, this beloved landmark has stood the test of time while fast food chains have come and gone all around it.
With a 4.6-star rating from nearly 3,000 happy customers, it is clear that something special is happening behind that little order window. Whether you are a lifelong local or just passing through, a stop at Eastside Big Tom feels like a delicious trip back in time.
Washington’s Oldest Drive-Thru: A Living Piece of History
Before drive-thrus were on every corner, Eastside Big Tom was already handing burgers through a window. Open since the late 1940s, this Olympia institution holds the title of Washington’s oldest drive-thru restaurant — and it wears that badge proudly.
Walking up to the window feels like stepping into a postcard from another era.
The building itself has a charming, no-frills look that reminds you of a time when food was simple, honest, and made with care. Nothing about it tries too hard, and that is exactly what makes it so appealing.
Locals have been pulling up to this same spot for generations, passing the tradition down to their kids and grandkids.
History does not always live in museums. Sometimes it lives in a little burger shack on 4th Avenue, still open and still serving up something worth remembering.
That kind of legacy is truly rare.
The Iconic Big Tom Burger You Have to Try
Ask any regular at Eastside Big Tom what to order, and they will tell you the same thing without missing a beat: get the Big Tom. This signature burger has been the heart of the menu for decades, and one bite explains exactly why people keep coming back for more.
The patty is cooked fresh and served hot, topped with their famous house spread — a tangy, mustard-based sauce locals affectionately call “the goop.” It is bold, savory, and unlike anything you will find at a chain restaurant. One reviewer described it as tasting better than Burgerville’s spread, with a flavor almost reminiscent of egg salad.
Fair warning: if mustard is not your thing, you might want to skip the goop. But for everyone else, it is the kind of sauce that turns a good burger into an unforgettable one.
Order it at least once.
The Famous Goop Sauce That Keeps People Talking
There is something almost legendary about a sauce that gets its own nickname. At Eastside Big Tom, that sauce is called “the goop,” and it has developed a fan base all its own.
Customers rave about it in review after review, and some people admit they drive all the way to Olympia just to taste it again.
Made with a mustard base and layered with pickles, the goop adds a punchy, tangy kick that brings the whole burger together. It is the kind of condiment that surprises you — even people who claim they dislike mustard have admitted to enjoying it once they tried it on a Big Tom.
The goop also pairs wonderfully with the crinkle-cut fries, turning a simple side into something worth dipping again and again. If a sauce has its own loyal following, you know the restaurant is doing something right.
Do not skip it.
Milkshakes in Flavors You Would Never Expect
Milkshakes at Eastside Big Tom are not an afterthought — they are practically a main event. The shake menu goes far beyond vanilla, chocolate, and strawberry, offering creative flavors like marshmallow, butterscotch, Dr Pepper, and peanut butter.
You can even mix two flavors together to create your own personal favorite.
Reviewers consistently call these shakes some of the best they have ever had. One customer raved about the marshmallow shake, saying it is not a flavor you see at many places.
Another called the butterscotch shake “the best,” and a Dr Pepper milkshake earned its own enthusiastic fan in the reviews section.
Be ready for a thick pour — these shakes are seriously dense and creamy, the kind that require a wide straw and a little patience. They arrive ice cold and full of flavor, making them the perfect companion to a hot, fresh burger on any afternoon.
Dinosaurs Everywhere: The Quirky Decor That Steals the Show
Nobody warned the first-time visitors about the dinosaurs — and honestly, that makes the surprise even better. Eastside Big Tom’s outdoor seating area is filled with dinosaur figures, creative signs, and playful decor that turns a simple burger stop into a full-on experience.
Kids absolutely lose their minds over it, and adults are not far behind.
Each picnic table has a bin filled with dinosaur figures for guests to play with while they wait for their food. Dinosaur sound effects play periodically throughout the outdoor area, adding an extra layer of fun to the atmosphere.
Some reviewers have compared it to a mini theme park hidden inside a burger joint.
The decor is creative, lovingly put together, and completely unexpected for a drive-thru. Whether you are five years old or fifty-five, stumbling upon a T-rex next to your crinkle fries is guaranteed to put a smile on your face.
It is pure, unfiltered joy.
Outdoor Seating With Covered Comfort Year-Round
Washington weather can be unpredictable, but that does not stop Eastside Big Tom from keeping their guests comfortable outside. The outdoor seating area features covered spaces with heaters overhead, making it a surprisingly cozy place to enjoy your meal even on a chilly or rainy Pacific Northwest afternoon.
Reviewers have mentioned eating comfortably in the rain without feeling miserable, which is no small feat in Olympia. The picnic-bench setup gives the space a casual, relaxed vibe that matches the restaurant’s no-fuss personality perfectly.
There is plenty of room to spread out, and parking is available on both sides of the building.
When the weather is sunny, the outdoor area becomes an especially magical spot — surrounded by dinosaurs, filled with families, and buzzing with a cheerful energy you rarely find at modern fast food spots. Rain or shine, sitting outside at Big Tom feels like a little adventure all on its own.
Crinkle-Cut Fries Worth Ordering Every Single Time
Crinkle-cut fries have a nostalgic charm that flat fries simply cannot match, and Eastside Big Tom’s version delivers on that promise. Reviewers consistently describe them as hot, crispy, and satisfying — exactly what a good fry should be.
They show up fresh and golden, holding their crunch even as you make your way through your burger.
Pair them with the goop sauce and you have got yourself a side dish that threatens to outshine the main course. The ridged shape holds onto sauce beautifully, making every dip count.
One reviewer even called them some of the best fries around, especially when enjoyed alongside the restaurant’s signature condiments.
Admittedly, not every reviewer has been head over heels — one mentioned the oil could use a change — but the majority of guests walk away impressed. For a classic drive-thru side, these fries hit the mark more often than not.
Order a large.
Friendly Service That Makes Every Visit Feel Personal
Fast service and friendly faces are a combination that is harder to find than you might think, but Eastside Big Tom seems to have nailed both. Reviewers repeatedly mention how warm and efficient the staff are, with one customer noting they were in and out in under two minutes without feeling rushed or ignored.
There is a bell at the ordering window that guests ring for service, and the team responds quickly to make sure no one waits too long. That small, old-fashioned touch adds to the charm of the whole experience.
One guest even left her purse behind and returned to find it safe, with the entire crew already aware and ready to help.
Little moments like that say a lot about the people working at a place. At Eastside Big Tom, the staff treat customers like neighbors rather than just transactions.
That kind of hospitality is exactly what keeps people coming back year after year.
Gluten-Free Buns for Every Kind of Burger Lover
Finding a classic, old-school burger spot that also caters to dietary restrictions is genuinely exciting. Eastside Big Tom offers gluten-free buns, making it possible for guests with gluten sensitivities to enjoy the full Big Tom experience without compromise.
That kind of thoughtful inclusion goes a long way for families with mixed dietary needs.
One reviewer specifically highlighted this option, expressing real appreciation that such a traditional spot had made the effort to accommodate gluten-free customers. It is not something every small, independent restaurant bothers to offer, which makes Big Tom stand out even more from the crowd.
The rest of the menu stays true to its classic roots — fresh patties, house-made sauce, crispy fries, and indulgent shakes — so gluten-free guests get to enjoy the same beloved flavors as everyone else. Nobody has to feel left out at this burger window, and that is a genuinely wonderful thing to be able to say.
A Puppy Patty for Your Four-Legged Road Tripper
Road trips with dogs just got a whole lot tastier. Eastside Big Tom offers a puppy patty — a plain burger patty made especially for your furry travel companion.
It is a charming, thoughtful menu item that instantly won over pet-loving customers and their tail-wagging co-pilots.
One reviewer gushed about how thrilled their dog was to receive the special treat, calling it an unexpected highlight of the visit. The concept fits perfectly with the restaurant’s warm, community-minded personality.
Not every drive-thru thinks about the four-legged passengers in the back seat, but Big Tom does.
One note of caution from a reviewer: be very specific when ordering the puppy patty if your dog has sensitivities, as seasoning can occasionally slip through. Communicate clearly at the window to make sure your pup gets a safe and happy meal.
When it goes right, though, it is absolutely the cutest drive-thru moment imaginable.
Giant Games and Family Fun in the Outdoor Area
Eastside Big Tom is not just a place to eat — it is a place to actually hang out and have fun. The outdoor area features giant versions of classic games like Jenga and Connect Four, giving families and groups something entertaining to do while they wait for their food or linger after finishing their meal.
One reviewer, a self-described “grown kid” without children of his own, admitted he had a blast playing with the games and exploring the space. That says everything about how well the outdoor area is designed — it appeals to literally everyone, regardless of age.
Combine the games with the dinosaur figures on every table and you have got an atmosphere that is genuinely unlike any other burger spot in the state.
Whether you are keeping little ones entertained or just enjoying something playful and unexpected, the game area adds real value to the visit. It turns a meal into a memory.
Fair Prices That Beat the Big Fast Food Chains
In an era when a basic fast food combo can easily run you fifteen dollars, Eastside Big Tom feels like a breath of fresh, affordable air. Reviewers consistently point out that the prices are fair — especially considering the quality of the food and the overall experience you get along with it.
One customer noted that the pricing made sense given how current fast food costs have skyrocketed everywhere else. You get a real burger made with care, hand-scooped shakes, and crispy fries without feeling like you need to check your bank account first.
That kind of value is increasingly hard to find in 2024.
For families especially, being able to feed everyone without a sticker shock moment at the window is a huge plus. Eastside Big Tom proves that quality and affordability can absolutely coexist — and that an independent, historic restaurant can still compete with the big names without breaking anyone’s budget.
Why Eastside Big Tom Belongs on Every Washington Bucket List
Some places earn their reputation through advertising. Others earn it the old-fashioned way — one great burger at a time, for more than 75 years straight.
Eastside Big Tom falls firmly in the second category, and that is exactly why it deserves a spot on every Washington traveler’s must-visit list.
From the legendary goop sauce to the marshmallow milkshakes, the dinosaur decor to the giant outdoor games, every element of this place adds up to something genuinely memorable. It is quirky without trying too hard, delicious without being pretentious, and welcoming without being overly polished.
That combination is rarer than it sounds.
Located at 2023 4th Ave E in Olympia, the restaurant is open Tuesday through Saturday from 11 AM to 7 PM. Whether you are a Washington native or just passing through, making the detour to Eastside Big Tom is one road trip decision you will absolutely not regret.
Go hungry.
