Some burger joints come and go faster than a lunch break, but one spot on Route 66 in Glendora has been at it since 1946. Its giant neon sign still towers over the parking lot, and the drive-thru line still wraps around on busy nights.
The counter here serves trays so loaded that one order of fries can feed a small family, and the kitchen stays open until 1 AM on weekends. Keep reading to find out what to order, when to go, how to skip the worst of the wait, and why this old-school stop has turned so many first-timers into regulars.
A Route 66 Address With a Loyal Following
Route 66 has plenty of famous stops, and Glendora claims one of the busiest. The Hat sits at 611 W Rte 66, Glendora, CA 91740, in the San Gabriel Valley of Southern California.
The place is officially a sandwich shop, though most people call it a burger stand or a diner. It works like a classic fast-food counter, with orders placed up front and trays called out by number.
The menu sticks to American standards. Burgers, fries, and hearty sandwiches make up the core, and nobody here is trying to reinvent the wheel.
That simple approach seems to work. The Glendora location has built up thousands of opinions online and holds a strong 4.6-star average, which is a big number for a spot that moves this much food every day.
Part of the appeal is how easy it is to reach. Route 66 runs right through town, so the restaurant is a natural stop for locals running errands and road trippers who want a taste of the old highway.
There is a drive-thru for people in a hurry. There is also a dining room and outdoor seating for anyone who wants to linger a bit.
Out-of-towners often say the place had been on their list for years before they finally made the trip. Once the tray lands on the table, most of them understand why the name keeps coming up.
Decades of Nostalgia on the Old Highway
Back in 1946, the neon sign went up and the grill got going. The burger business has kept rolling in Glendora ever since, which puts it in rare company for a counter-service restaurant.
That long run shows in the mood of the place. The setting leans into a classic 50s and 60s diner style, and many guests describe the whole experience as deeply nostalgic.
For longtime locals, a trip here can feel like a visit to an old friend. Some folks have been ordering from the same counter for years and still come back on a regular schedule.
For newcomers, it offers something different. It is a chance to eat at a Southern California staple that has not traded its personality for a modern makeover.
The giant sign is a big part of that identity. It acts as a landmark on Route 66 and makes the restaurant easy to spot from down the road.
Of course, a long history does not mean nothing has changed. Prices have climbed over the years, and a few regulars notice small shifts in how things are handled at the counter.
Still, the heart of the operation looks familiar. The menu stays focused, the trays stay full, and the sign keeps doing its job every single night.
The Burger Board, From Junior to Double
Burgers got top billing in the headline, so they deserve a close look. The lineup covers a lot of ground without getting complicated.
On the smaller end, the JR cheeseburger is a budget-friendly pick. It is not a giant, but pairing it with a side turns it into a full meal for well under the cost of a big dinner out.
Hungrier guests tend to step up to the chili cheeseburger. Fans of this one like to ask for extra mustard, and the counter handles that kind of request without fuss.
The double chili cheeseburger raises the stakes even further. It is a common choice for anyone who skipped lunch and plans to make up for it.
There is also a burger that borrows the restaurant’s signature sandwich meat and stacks it on top. People who order it tend to recommend it with real enthusiasm, and it has become a favorite way to get the best of both worlds.
A plain hamburger or cheeseburger is always an option too. Groups often mix and match, with one person on a classic burger and another on something loaded.
Custom orders are welcome. Staff can tweak toppings on the spot and call the changes out to the kitchen, so the finished burger matches what was asked for.
Portions That Laugh at Your Appetite
Here is a fair warning. Ordering one side per person is a rookie move at this counter.
The loaded fries come in a mound large enough to share between three or four people. Some groups have learned this the hard way after ordering two trays and barely making a dent in either one.
Onion rings and regular fries arrive in generous servings as well. A small burger plus a side can easily fill up one adult, and it keeps the bill under control.
For the truly ambitious, there is an off-menu move. Regulars sometimes ask for fries topped with chili, cheese, and the house sandwich meat, and the result is big enough to feed a table.
Families tend to appreciate the sharing math. One group of three adults and three kids found there were plenty of fries and rings to go around.
Not every trip is identical, though. A few longtime customers feel portions have shrunk a bit while prices have gone up, since items are now weighed.
Even with those notes, the word portions still comes up constantly when people talk about this place. The smart plan is to order less than you think you need, then go back for more if the table somehow clears it.
The Sandwich That Built the Legend
Burgers may be in the title, but the restaurant is best known for one signature sandwich. It is the item that turned this counter into a regional name.
The meat is sliced thin and piled high on a soft roll. People who love it say the sandwiches are packed with plenty of filling, sometimes enough for two people to split.
Many regulars order it dipped. A popular customization is adding extra pickles and extra mustard, and plenty of fans swear by that combo.
Small details can vary from trip to trip. Some guests notice their dipped order does not always come out dipped, and others mention the thin pieces can slip out if you are not careful.
A few folks also wish a side pickle came with it. That is a minor gripe, and most people still walk away happy.
The same meat shows up across the menu. It lands on burgers, gets piled onto fries, and makes its way into special requests.
Other sandwiches exist, such as roast beef and a beef dip. The general advice from repeat customers is to stick with the house specialty, since that is what the kitchen is famous for.
Clean Floors and Room to Spread Out
A spotless dining room is not always a given at a busy burger stand. At this location, cleanliness is one of the things people bring up again and again.
Guests describe the restaurant as immaculate and orderly. One fan joked that the room is clean enough to perform surgery in, which is high praise for a place that serves this much chili.
The layout is friendly to people with mobility needs. Aisles and doors are wide, so wheelchairs and strollers can move through without much trouble.
Seating is plentiful inside. On nice evenings, the outdoor seating area becomes a relaxed place to eat and hang out after dark.
Parking is another plus. The lot has plenty of spaces, which matters when the dining room fills up at peak times.
One small change is worth knowing about. Condiments and napkins used to sit out on the counter, but now they are not always there, so it helps to ask for extras when ordering.
Some regulars also recommend grabbing a few extra napkins to wipe down a table during the rush. It is a small step that makes the meal go smoother, especially with loaded fries in play.
Drive-Thru Lines and a Speedy Counter
Long lines can scare people off, but they do not tell the whole story here. The drive-thru often backs up, yet it tends to move faster than it looks.
Several drivers have waited in a long row of cars only to get their food surprisingly quickly. Friendly staff at the window help keep things moving.
Inside, the system is simple. Orders are placed at the counter, and cashiers call out any special requests so the kitchen crew can hear them clearly.
Order numbers are called when food is ready. On a slower morning around 11 AM, the dining room can be fairly quiet even while the drive-thru stays busy.
During rush periods, patience helps. The place is often full of people, and food can take a little while, though most fans say the wait is worth it.
Staff experiences vary. Many people describe the team as friendly, quick, and efficient, while a few say the counter can be hit or miss on crowded days.
A handy trick for skipping the car line is to park and walk in. The counter sometimes moves faster than the drive-thru, especially before the lunch crowd arrives.
Free soft drink refills are a nice bonus for anyone who decides to stay a while.
Late-Night Hours and What to Budget
Night owls get a real break at this address. The kitchen stays open late every day of the week.
Monday through Wednesday, hours run from 10 AM to 11:30 PM. Thursday, Friday, and Saturday stretch from 10 AM all the way to 1 AM.
Sunday hours are 10 AM to 11 PM. That schedule makes it one of the easier spots in the area for a late-night meal after a movie, a game, or a drive to see holiday lights.
Most meals land in the $10 to $20 range per person. A quick snack can come in under $10, especially with a smaller burger and a side.
Prices have gone up noticeably over the years. Longtime regulars mention it, but many still feel the portion sizes help balance out the cost.
Sharing is the best way to stretch a budget. Since one order of loaded fries can feed several people, a group can split sides and save a few dollars.
Menu details and updates are posted on the official website at thehat.com. It is a good idea to check before heading out, since the drink lineup sometimes changes, with seasonal options like horchata occasionally taking a regular spot on the fountain.
Worth the Stop for Burgers and Tradition
After more than seven decades on Route 66, the formula still holds up. Big trays, fair prices for the amount of food, and late hours keep people returning.
Families will find plenty to share. Groups of friends will appreciate the loaded sides, and solo diners can grab a small burger for a cheap bite.
Late-night eaters have an easy win here. With service until 1 AM on weekends, it fills a gap that many restaurants leave open.
First-timers from out of town often leave impressed. They tend to understand the constant crowd after one meal.
It is not perfect. Prices have climbed, the counter can get hectic, and a dipped order may not always come out exactly as requested.
Those quirks rarely outweigh the good parts. The clean dining room, the quick drive-thru, and the generous servings earn the place its solid local reputation.
For anyone planning a Route 66 day in the San Gabriel Valley, this Glendora stop makes a fitting detour. Come hungry, bring a friend to split the fries, and save a moment on the way out to glance back up at that famous neon sign, which has been keeping watch over the burgers since 1946.
