Only three people on Earth know the recipe for the olive sauce on this burger. One of them is a longtime employee.
The other two are family.
That creamy, salty, briny sauce dates back to the 1920s. A great-grandmother created it, and the family has guarded it ever since.
Lawmakers in Michigan even gave the city a sweet title because of it.
I love that a single spread can carry that much history. The beef gets ground fresh daily and never sees a freezer.
The walls hold antique dolls, old soda signs, and wagon wheels.
I can’t imagine a better excuse for a road trip than a burger with a secret. Some folks make the drive from far outside the state.
So what makes a little olive sauce worth all those miles?
Three People Hold The Secret, And None Of Them Are Talking
Weston’s Kewpee Sandwich Shop, also known as Kewpee Sandwich Shoppe, keeps one recipe locked tighter than a bank vault. The olive sauce on its famous burger is a family secret from the 1920s.
Gladys Bowlin, sometimes called Gladys Weston, created that original spread. She’s the great-grandmother of current owner Autumn Weston.
Today only three people know the exact formula. Autumn knows it, her father Gary knows it, and longtime employee Tammie Bunker knows it too.
That’s a pretty exclusive club. Most families struggle to keep a birthday surprise quiet for a week.
The sauce gets described as a delicate balance of mayonnaise and brine. Expect creamy, salty, and briny flavors all in one swipe.
Here’s a fun twist for olive lovers. The olives live in the sauce, not mixed into the meat itself.
That detail matters if you’re picturing something different. The sauce sits on top, letting the beef and the tang share the spotlight.
Not sure about olives? The olive burger is still the signature order here, so it’s the natural first pick.
Worst case, you learn something about yourself. Best case, you join a very long line of converts.
Pick Your Size Wisely, Because Kolossal Means Business
Size choices at this Lansing shop come with names that sound like wrestlers. Regular, King, and Kolossal are your three olive burger options.
The Regular weighs in at 2.5 ounces. It’s a classic, tidy option for lighter appetites or anyone saving room for pie.
Step up to the King and you get a quarter-pounder. That feels like the sweet spot for a solid weekday lunch.
Then there’s the Kolossal, a half-pound burger. The spelling with a K is a cute nod to the Kewpee name, and the portion backs it up.
Every patty starts as certified Angus beef. It’s ground daily, it’s fresh, and it’s never frozen.
That’s a big promise for a small spot. Plenty of chains can’t say the same thing.
Burgers here cook well-done as the standard style. If you usually ask for medium-rare, plan ahead before you order.
A smart move for first-timers is matching the size to the plan. Sightseeing afterward?
The King might keep you moving.
Heading home for a nap? Go Kolossal and call it a day well spent.
Lawmakers Gave This City A Burger Title, And It Stuck
In 2023, the Michigan Legislature made something official. Lansing became the Olive Burger Capital of the World.
Not every city gets a food crown from its own state lawmakers. Lansing earned this one, and Weston’s Kewpee Sandwich Shop is a huge part of that story.
Think about how that works. A sauce born in a family kitchen in the 1920s ended up recognized by the state government.
That’s a long road from a home recipe to a legislative honor. Gladys Weston probably never pictured her spread getting that kind of attention.
The title also explains why curious eaters travel here. If a city carries a world capital label, you naturally want to taste the proof.
Olive burgers show up at other spots around the state too. Still, few places can claim a family recipe this old.
For food fans, that’s the real draw. You’re tasting a piece of Michigan food history, not just a lunch special.
Bragging rights come free with every order. Telling friends you ate at the source in the Olive Burger Capital sounds pretty great.
Kewpie Dolls Watch Over Every Bite You Take
Antique Kewpie dolls line the walls inside this shop. Their wide eyes and tiny smiles give the room a sweet, slightly playful charm.
The dolls aren’t random decor. The Kewpee name actually comes from the famous Kewpie doll, so they’re part of the family tree.
Look around a little more and the details keep coming. Vintage Coca-Cola signs and wagon wheels add to the old-school feel.
Cozy booths give you a comfy spot to settle with your tray. The wooden tables show the kind of wear that only decades of lunches can create.
The whole place feels like a culinary time capsule. It’s nostalgic without trying too hard.
Kids may find the dolls adorable. Some adults might find them a tiny bit spooky, which honestly adds to the fun.
Take a minute to wander your eyes across the walls before you eat. The decorations tell the story of a business that’s lasted more than a century.
Phones out for photos? The doll collection makes a great snapshot to share.
Just maybe don’t stare back too long.
Blue Brick And Art Deco Make A Classy First Impression
A blue brick Art Deco facade greets you at 118 S Washington Square, Lansing, MI 48933. It’s a handsome storefront with a distinct retro style.
Art Deco design was big in the early 1900s. That fits nicely with a shop that opened its doors in 1923.
The location puts you right in downtown Lansing. That makes it easy to pair lunch with other plans in the heart of the city.
The Michigan State Capitol sits close by. A tour followed by an olive burger sounds like a well-rounded afternoon.
Downtown also means you may need to think about parking. Leave a few extra minutes so you’re not rushing toward your burger.
The building looks modest from the street. Plenty of people miss it at a glance, so keep your eyes on the address.
Once you spot that blue brick, you’ll remember it. It stands out from the newer buildings around it.
Snap a quick picture of the facade before heading inside. It’s a fun way to remember a stop at Kewpee Sandwich Shoppe.
A Century Of Family Burgers Started With A Hotel Hamburg
Back in 1923, this Lansing shop joined a chain called Kewpee Hotel Hamburgs. That chain got its start in Flint, Michigan.
The Weston family has owned the Lansing location for over 100 years. Autumn Weston now leads as the fourth generation.
Four generations in one business is rare. Most families can’t agree on a dinner spot for four generations, let alone run one.
The Kewpee chain also gets credit for some clever ideas. The flat-bottomed bun and the hamburger deluxe are two of them.
A deluxe usually means mayonnaise, lettuce, and tomato. Pretty standard now, but someone had to think of it first.
Some sources even say Kewpee inspired the square burgers at Wendy’s. That’s a fun connection for burger history buffs.
Today, this spot stands as one of the few original Kewpee locations left. That’s true in Michigan and across the wider Midwest.
So every bite carries some serious backstory. You’re eating where hamburger history actually happened, which makes for great lunch conversation.
Cherry Burgers, Coney Dogs, And Other Surprises On The Board
Olive skeptics, relax. The menu here goes well beyond that famous sauce.
Classic hamburgers and cheeseburgers are ready for purists. There’s also a turkey burger, a veggie garden burger, and a cherry burger for something different.
A cherry burger feels very Michigan. The state loves its cherries, so that option makes perfect sense.
Sandwich fans can pick from a Kewpee Klub, Grilled Turkey, or a Crispy Chicken Sandwich. A Fish Sandwich and a Vegetable Sandwich round things out.
Grilled cheese is on the list too. It’s an easy win for younger eaters or anyone craving comfort food.
Hot dog lovers can grab a Koegel Coney Dog. Koegel is a well-known Michigan name, so that’s a fitting local touch.
Homemade soup, fresh salads, and homemade chicken salad cover lighter appetites. French fries and chili are available as sides.
One tip helps a lot. Items are ordered individually, so add your fries separately if you want them with that burger.
Save Room, Because The Pie List Is Long
Very Berry, Apple Crisp, Strawberry Rhubarb, and Cherry. That’s only the first half of the fresh-baked pie lineup.
Peach, Pecan, Sugar Cream, and Lemon Krunch complete the list. Picking just one could become the hardest decision of your day.
Sugar Cream pie is an old-fashioned favorite. Lemon Krunch sounds like it brings some fun texture to the table.
Not a pie person? Malted milks and Frosted Malts offer creamy, cold relief after a salty burger.
Soft Frozen Yogurt is also on the menu. It’s a lighter way to end the meal on a sweet note.
Then there’s the hand-crafted root beer. Made in-house, it’s a drink with real personality.
Root beer and a burger is a classic match. Add an olive burger and you’ve got a lunch that tastes like a different era.
Here’s a sneaky plan. Grab a slice of pie to go for later, because future you will be grateful.
Plan Around The Weekday Hours Or Miss Out
Weekends are off the table at Weston’s Kewpee Sandwich Shop. The shop is closed on Saturday and Sunday.
Weekday hours start at 10:30 a.m. and wrap up in the afternoon. Closing times can vary by day, so check before you head out.
That schedule matters for road trippers. Driving across Michigan only to find locked doors would be a sad ending.
Ordering works counter-style. You place your order, take a number, and staff bring your food to you.
Dine-in and takeout are both options. Takeout works great if you’re eating on a downtown bench or heading back to work.
The vibe is fast-casual. It’s quick and relaxed rather than fancy or formal.
Arriving right at opening gives you the most breathing room. It also leaves time for pie, which is always a smart plan.
Kewpee Sandwich Shoppe has served Lansing for over a century. A little planning helps you become part of that long, tasty story.
