☀️ Weather like this is way too nice to be sitting inside all day!

Grab a smash burger, some fries, and head out to the patio at the Old Base Factory Food Hall. 😎🍔

There’s plenty of outdoor seating, an outside bar, TVs, and a whole lot of room to hang out and enjoy the day.

There’s no judgment at Smash Jacks… especially when the cheese sauce comes out. 😋

Dip the burger in it. Pour it over the top. Get a side for the fries. At this point, we’re just here to support your decisions. 🧀😅

Because apparently a double smash burger with crispy bacon wasn’t enough… somebody decided it needed a full cheese bath too. 🤤

Come grab your favorite Smash Jacks burger and don’t be afraid to ask for that cheese sauce on the side. 👀

🍔 All burgers are served with fries or coleslaw!

⏰ Open daily at 11AM!

ONE MONTH OF SMASH JACKS! 🍔🧡

It’s officially been one full month since we opened our doors, and we just want to say THANK YOU. 👊

The last month has been crazy in the best way possible. From opening night and that nonstop line, to seeing familiar faces come back again and again, the support you guys have shown us has honestly meant so much.

Thank you to everyone who has stopped by, tried one of our burgers, brought your friends and family, shared our posts, told someone about us, or came back for another round. Every single order has helped support our little business, and we appreciate it more than you know.

We’re still learning, growing, and getting better every day, and we’re excited to see where Smash Jacks goes from here.

Here’s to ONE MONTH down and a whole lot more burgers ahead. 🍔🙌

Thank you, O’Fallon! 🧡

Friday calls for a burger, a big pile of fries, and maybe a little Moo Sauce on the side. 😎

If you came to Smash Jacks and told yourself you were just getting a burger… yeah, that plan probably ends at the cookie counter. 😆

We’ve got the burgers, we’ve got the fries, and for the people who magically still have room, we’ve got cookies waiting for you too. 🙌

🍪 Cookie flavors:
Sugar ✨
S’mores 🔥
Chocolate Chip 🍫

You can say it’s for later. We won’t ask questions. 🧡
