Some cities guard a secret recipe, and St. Louis guards a cup that can be held upside down. On busy nights, the parking lot on the south side of town fills with families, road trippers, and school groups, all waiting at a small walk-up window.
Nobody seems to mind the line, because it moves fast and the payoff is a thick frozen custard treat called a concrete. Locals have been making this run since 1929, and many grew up doing it with their own parents.
The stand has no indoor tables, no fancy decor, and no plans to change. What it does have is a long menu, a famous flip-it-over ritual, a gift shop, and a small museum.
Here is everything worth knowing before joining the crowd.
A Walk-Up Window on Old Route 66

Ted Drewes Frozen Custard sits at 6726 Chippewa St, St. Louis, MO 63109, in the United States. The stand lines a stretch of historic Route 66, which explains why so many cross-country drivers pull in.
It is officially an ice cream shop, yet the menu centers on frozen custard. Every order goes through a walk-up window, so the whole experience happens outdoors.
The building is white and simple, topped with classic roadside signage. That retro look fits right in with the old highway it serves.
Plenty of travelers plan their Route 66 trips around this single stop. Some are heading toward Chicago, while others are just passing through Missouri for a day.
For locals, the address is less a destination and more a habit. Kids who came here decades ago now bring their own children to the same window.
The popularity shows in the numbers too. The stand holds a 4.8-star average across more than 12,000 opinions on Google, a remarkable figure for a place with no dining room.
So the setting is humble, but the reputation is anything but small, and the story behind it stretches back nearly a century.
Nearly a Century of Custard Tradition

Back in 1929, St. Louis started a tradition it has never dropped. Generations of residents have been lining up at Ted Drewes ever since, and the place now counts as a true city landmark.
Many families treat a visit as a rite of passage. Some regulars have been coming for more than 30 years, starting when they were small children.
That kind of loyalty does not happen by accident. The formula has stayed refreshingly simple: a vanilla custard base, a long list of add-ins, and fast service at the window.
The stand also carries a reputation beyond city limits. It has picked up awards over the years, and it is often called one of the best frozen dessert stops in the country.
Nostalgia plays a big role too. For many St. Louisans, a trip here is tied to summer evenings, ballgames, and family outings.
Out-of-town guests usually get dragged along by local friends who insist on it. The result is a crowd that mixes lifelong fans with wide-eyed first-timers.
History is the foundation here, but the real star sits inside a cup, and it has a very sturdy name.
The Concrete and Its Famous Flip

Few desserts come with a party trick, but this one does. Staff members often turn the cup upside down before handing it over, proving the concrete will not budge.
That is the whole idea behind the name. A concrete is frozen custard blended with toppings until it becomes thick enough to defy gravity.
The custard itself is made with egg yolks, which sets it apart from regular ice cream. The result is smooth and rich, with no icy bits.
Because it is so dense, a concrete asks for patience. People tend to slow down and work through it spoonful by spoonful.
Toppings are mixed in generously, so add-ins show up in nearly every bite. The Turtle concrete, with hot fudge, caramel, and pecans, is one of the most popular orders.
Other favorites include cookie dough, peanut butter cup, Heath bar mocha, and Mississippi Mud Pie. Some fans also build their own with picks like pistachios, hazelnuts, or raspberry.
The flip is fun to watch, and first-timers usually grab their phones for it. Once the cup is right side up again, the menu still has plenty more to explore.
Specials With Hometown Names

Ordering here can feel like learning a local language. The menu is packed with specials, and many of the names are playful nods to St. Louis.
Cardinal Sin is a big favorite, and it often wins over first-time groups. Other named options include Terramizzou, Dutchman Delight, and Muddy Mississippi.
Some specials mix two flavors, while others combine three. That gives curious eaters a reason to come back and try another one next time.
Size choices help with that plan. Mini and small portions make it easier to sample, which suits road trippers who want a quick bite before getting back on the highway.
Fruit lovers have options too. Strawberry, pineapple with real chunks, banana, and a blueberry lemon graham cracker combo all appear in orders, and lemon crumb gets plenty of mentions.
Staff members are known for explaining the menu clearly. That helps a lot when the list feels long and the line behind you keeps moving.
A good strategy is to pick one special and one custom creation, then compare notes. Arguments over the best combo are practically part of the tradition.
Sundaes, Shortcake, and Baseball Helmets

Concretes get the headlines, but the rest of the menu deserves a look. Strawberry shortcake is among the most talked-about items, and it comes across as fresh rather than overly sweet.
The hot fudge sundae is another classic. It keeps things simple, and that simplicity is part of its appeal.
Kids tend to love the sundaes served in mini baseball helmets. In a city that cares deeply about baseball, that detail fits perfectly.
There is also root beer on the menu. It makes a handy sidekick for anyone who wants something to sip alongside a dense custard.
Plenty of people stop by after dinner elsewhere, planning to grab one small treat. Then the menu happens, and suddenly the order includes a concrete, a sundae, and a shortcake.
Portions are generous for the most part, though a few people feel a cup could be fuller. Prices lean slightly higher than some dessert shops, yet many say the size makes up for it.
One honest heads-up: custard can soften quickly on warm days, so eating soon after ordering is the smart move.
Long Lines That Somehow Fly By

Crowds here are not a rumor. The stand gets packed, even at 10:30 at night on a weekend.
Friday evenings around 8:30 can be jammed, and school groups sometimes fill the lot during the day. Weeknights draw steady crowds as well.
Still, the line has a reputation for moving quickly. Many longtime fans say they rarely wait more than a few minutes, even when the queue looks intimidating.
The secret is a very efficient crew. Orders come out fast, and the workers stay friendly while handling a nonstop rush.
The parking lot is usually full, so a little patience helps when finding a spot. Arriving with a plan for what to order also speeds things along.
Groups can split up, with one person grabbing a parking space while others hold a place in line. It is a small trick, but it saves time on busy nights.
For some people, the wait is half the fun. Watching cups flip at the window and chatting with neighbors in line builds plenty of anticipation for the first spoonful.
Parking Lot Hangouts and People Watching

Forget booths and tables, because the parking lot is the dining room. Ted Drewes has no indoor seating at all.
Most people simply stand around with their cups and chat. There are benches off to the side of the parking area for anyone who wants to sit.
That setup creates a lively, social scene. Families, couples, and travelers all gather in the same space, which makes for great people watching.
The atmosphere feels local and old school. It is the kind of classic Midwest stopover that seems to belong in a road trip photo album.
Children fit right in, and the environment is very family friendly. Helmet sundaes and mini sizes make it easy to keep younger guests happy.
Road trippers in RVs and cars also mix into the crowd. Many are crossing Route 66 and treat this as a highlight of the journey.
Fans say the stand works in any season, not just summer. Around the holidays, the lot also becomes known for Christmas trees, adding another reason for winter stops.
A Gift Shop and Mini Museum Next Door

Dessert is only part of the outing. Right across the parking lot sits a gift shop, and it doubles as a small museum about the history of the stand.
The museum offers a look back at how this custard stop became a St. Louis institution. It is compact, so it fits easily into a short visit.
Souvenir hunters can pick up merchandise to bring home. It makes a nice memento for Route 66 travelers collecting stops along the way.
Employees in the shop are friendly and know the company well. They can share background on the business for anyone curious about its past.
Families often split their time here, browsing while the line outside thins out. Others wander over after finishing their custard.
The shop gives the visit more substance than a quick grab-and-go. It turns a dessert run into a small slice of local history.
Many first-timers say they did not expect the museum at all. That surprise tends to become one of the happier parts of the trip.
Hours, Planning Tips, and a Sweet Verdict

Good news for night owls: the window stays open late. Hours run from 11:00 am to 10:30 pm every day of the week.
That schedule makes it easy to plan an afternoon break or a late dessert after dinner. Weekend nights draw the biggest crowds, so earlier visits may feel calmer.
Since seating is outdoors, dressing for the weather is wise. Benches are limited, so expect to stand on busy evenings.
Prices are a bit higher than some frozen dessert shops. Portions tend to balance that out, and mini sizes keep costs down for sampling.
First-timers should try a concrete, since it is the signature order. Adding a special or a shortcake gives a broader taste of the menu.
Not everyone leaves convinced the hype is fully earned, and a few find the custard closer to soft serve. Most, though, call it a must-do stop in St. Louis.
With nearly a century of history, a quirky flip, and a crowd that keeps coming back, this window has earned its place. One upside-down cup is all it takes to understand why.
