Frontier Perk Cafe

Fantastic! We had the short rib grilled cheese and the shrimp poke bowl. Both we amazing! Service was fast and staff was very friendly.

We had a wonderful experience. Great staff, intimate atmosphere, smart searing policy that got us seated immediately, and great food and desserts. We'll definitely return.

First time there today and the food was delicious. Had a guava pastry, and I’m an island girl so I get excited when I see a rare Guava anything here. It was delicious. Can’t wait to try other things. Side note: it is a really small place so expect to sit outside or take breakfast to go if the tables inside are full.

Excellent food and atmosphere. Friendly staff. Probably the best gooey buttercake I've ever eaten, I would highly recommend this place!

So far not impressed. Mahi Tacos were small and I'm not sure fish was even in it. Seems they have room for improvement.

Excellent cafe with top tier service and food/coffee.

Delicious! Customer service was good. Friendly. I got the tradition breakfast and an ice salted carmel latte. Good feeling in there.

Great food and a fine establishment for sure. High praise to the staff for delivering great service and quality.

Was looking for a good breakfast place to visit and stumbled across this place on Google. Didn't realize the limited seating capacity until we got there, but got lucky with getting a table within a couple minutes. The food was fresh and hot and certainly the best breakfast I've had in quite some time. Staff was super friendly and helpful, a nice change from some of the other establishments I had previously visited in St Louis just the previous day. Very charming place, would definitely recommend to anyone visiting St. Charles.

Best Cubano sandwich I’ve ever had. Turkey club was fresh, their produce was cold and great quality. Coffee was fantastic as well, try their lavender bliss for a nice sweet coffee drink to go with the spring vibes outside on old main st. St.Charles. All in all this is our new favorite place to eat in St.Charles.
