Small but mighty! There is barely any seating or standing room but who cares....they are serving up deliciousness! There was a line out the door and a wait but soooo worth it. Honestly, it was the best thing I ate my entire St. Charles/STL visit. I ordered a breakfast sandwich with fried egg, avocado, cheese and a flaky buttery croissant and it was PERFECT. Huge and filling! It came with the most delicious roasted potatoes I've ever had. OMGNESS sooooo good!!! I can not wait to go back and order the same breakfast sandwich. Then go back later in the day and try the pot pie. read more

Food was great, loved the ambiance and staff. Had the Alex's breakfast burrito and short rib stack. Coffee was. Ice and strong

Super cute and quaint. Met friends for lunch and the shrimp avocado salad amazing. I will definitely go back.

CanNOT say enough good things about this place! First off, I got the Pumpkin Pie Latte and it was PERFECT! I usually ask for 1/2 the flavoring because at a lot of places, these type of drinks tend to be overwhelmingly sweet. This one was NOT. Hubby ordered the Honey Hot Chicken Biscuit and it was OH SO GOOD! I had to try the Meat Pie and I definitely should've ordered TWO. Also, very good! My one complaint? They need to be BIGGER, so more folks can fit in!!! Service was GREAT even though they'd been slammed after a marathon finished up. This place is just GREAT! Will be back. read more

I have been a fan of Frontier Perk Cafe for a long time. However, today, I finally stopped by the new location (new in 2024). I regular stop by the previous location for a quick coffee, now called St Charles Coffee and Creperie. The new Frontier Perk Cafe space is historical and gorgeous as well as comfortable. Service was great as it always has been, and I ordered Mahi Mahi Tacos with a Salad (upgrade) as my side. Also, I added a seasonal special Maple Brown Suger Oat Latte. If you have not tried Frontier Perk Cafe on Historic Main Street in St Charles, you should add to your to-do list - you won't be disappointed. read more

This has become our new fav spot for breakfast & brunch! Breakfast tacos w a side of warmed guava pastry! We have tried almost everything in the menu and it too is a hit. No complaints here. Order first, then be seated. Be patient and respectful of others enjoying their time. If you are in a hurry or an impatient person, this is not the place for you! Service is top notch! read more

Went to the new location, which provides much more seating and is very nice inside. "Alex's breakfast tacos" were delicious! I look forward to having them again. I also love their coffee, ordered a caramel macchiato but they have seasonal options such as the coconut matcha latte and lavender bliss. I only gave 4 stars because I feel they haven't gotten the staffing and service times down to smoothly operate their new table service style. The staff were very kind and apologetic about the wait and were doing what they could! read more

The short rib & egg breakfast was D-lish!!! The service was professional and the atmosphere charming. Definitely coming back!

I've stopped in here a few times, sometimes for breakfast, other times for lunch. I loved the shrimp salad for lunch! The service is pretty dang quick, even when they're busy. You can order ahead if you're in a hurry though. The dining room is cozy and had a wonderful fall breeze last time I was in there. Highly recommend stopping in if you're walking around the area. read more

I really don't understand the good reviews on Frontier Perk Cafe. This place was terrible! We did a takeout order of a cup French Onion Soup. We received 3 ounces of soup! I measured it because I couldn't believe it. We called them and were told that their cup size is 3 ounces! We also ordered the brisket grilled cheese which didn't even have 2 tablespoons of meat on it with little cheese. The Shrimp Po'boy we ordered had lettuce, 4 small pieces of shrimp, with a thin slice of a rotten tomato! On the Po'boy chips was a black hair! This was by far the worst meal I have ever had around not only St. Charles but St. Louis! The manager/owner my wife talked to about the soup should be ashamed of what we were given, and yet he wasn't. Wish we didn't leave a good tip in the jar on top of this bill! Spent almost $50. total on this! read more

My wife needed some spices at the spice shop next door and it was very busy, so I popped into this little cafe instead because I smelled coffee. I didn't really look at their menu much because when I looked at the menu board, my eyes immediately locked on Cubano. I hadn't had a Cubano in quite a long time so I had to order it. It is very strong espresso with lots of sugar. The price was good, but I did think there could have been a few more sips in there. I realize it's espresso so you don't get or want too much, but just a little more would be good. There was just about enough sugar added, but the coffee was just a little bitter tasting. The staff was nice and it was a nicely decorated cafe. I'll have to stop by again sometime to check out some more menu items. read more

We were very excited about having brunch at this little cafe while we were here visiting family, but unfortunately I was pretty disappointed in the service. Our family sat outside on the patio since the inside was busy and all the tables were taken. The patio chairs have arms and are pretty snug and one of our family members needed a bigger chair or one without arms, so we grabbed an empty chair from inside. But when one of the servers came outside she took the chair back and said these chairs are for the inside only. We tried to explain that the other chair would be more accommodating for our family member and she refused to make any accommodations for us. As someone with multiple handicap members in my family, I've never seen a restaurant be so unaccommodating. I'm still pretty dumbfounded about the whole situation. If we hadn't already paid over $100 for our meal we would have left for sure. The food was good for a modern little cafe, but the service is below par. read more

Just went to their new location, it was AMAZING! I had the breakfast tacos and it was delicious as always. Our server Jen was hilarious and so welcoming! Definitely add this to your breakfast/brunch list! read more

The food, service, and atmosphere were awesome! 10/10 their coffees and daily specials were delicious.

Frontier Perk Cafe is something I have wanted to try since it opened. Unfortunately, with their hours being 8a-3p Tuesday through Sunday, it is a bit harder to get there, but I can understand why those hours are needed due to the dedication to the fresh drinks and eats. Upon walking into the cafe, you are greeted with a warm hello. The cafe itself holds an eclectic but new age feel being in Historic St. Charles. It was clean and had the aroma of fresh coffee being made. The ambiance created due to natural lighting and rustic wood reminded me of being in a peaceful cabin. Now, we get to the important part: the food. The front counter had quiche, pastries and meat pies to choose from. What I wanted was no longer on the menu (the lavender latte), but when I asked, they were still able to make it but it was not listed as they are making changes and updating their menu. I also ordered the bagel and lox that comes with cream cheese, smoked salmon, capers and pickled onion. I ordered a breakfast burrito with potatoes and a cold brew for my husband to go for his lunch later on. The wait was 10 minutes for everything. Not only did it take no time for my order, everything tasted fresh, the bagel was still warm, and you could tell the pickled onions were made recently because of their crisp and sour punch. The lavender latte was warm, creamy and felt like a hug. The price point for Frontier Perk is affordable to average, depending on what you get, for the fresh ingredients and dedication to making their food perfect. For 4 items, I was able to only spend $35 (that included a $6 tip). The only thing I would change about Frontier Perk Cafe is that they were open later so I could enjoy their amazing food any time of the day. I will now be recommending this place to anyone I know who is looking for a fantastic and welcoming brunch or lunch spot when visiting the St. Louis/St. Charles area. read more

A picture really can't capture how tasty the dishes were at Frontier Perk Cafe. They had a good variety in drinks and food as well as bakery/pastry items. We ended up getting their cappuccino, iced cafe latte, omelette, short ribs poached egg, and Cuban sandwich. Every single item was amazing. We were all exclaiming how this tiny cafe produced big flavors. Even though I don't normally drink coffee, I was so impressed with just a few sips of their latte. My family (coffee lovers) kept remarking how good their drinks were. We will have to be back for their Cuban pies (which were sold out by the time we were there). My only complaint was that the store itself was really quite hot, so for our baby's sake, we chose to sit outside and eat quickly before it started raining. I think a few nice fans inside would have helped keep the patrons sitting comfortably inside on a raining day. Otherwise, we had an amazing meal. And we will be back! read more

Found this place on Yelp and decided to try it with my daughter. I've never seen a place with a 5 star rating with 50+ reviews so I knew it was going to be great. Food was outstanding and the service was great as well. We had the biscuits and gravy and an order of pancakes and bacon. The menu has lots of variety and I saw the chicken and waffles being brought out to another table and it looked amazing - that will be what order the next time. It's a family run business which is great because I always like supporting a local establishment. You won't be disappointed! read more

Took my mom here with my kiddo to try somewhere new and it did NOT disappoint! The pricing is so fair and the employees are everything. My mom loved her chicken salad sandwich (which she gets everywhere so she has strong opinions lol) my Cobb salad was filled to the brim with toppings and not just lettuce and my daughter got the kids chicken strip and chips which she devoured. This is the perfect one-stop-shop for savory, sweet, a meal, a snack, some caffenation, you name it! Hidden gem! read more

It's been closing in on a year since I happened upon this gem of a restaurant and I haven't stopped going! And every time, the food has been consistently outstanding. I've never left hungry. In fact, this has become my daughter and my go-to every Friday for breakfast/lunch! My favorite menu items are the grilled mahi-mahi tacos (you will notice be disappointed)-3 tacos chock-full of goodness and flavors and textures. They come with a side of house made chips. I also recently found a love for their homemade chicken pot pie. It's a creamy, delectable dish with a light, crisp puff puff pastry on top. My breakfast favorite is their eggs Benedict. If you like eggs Benedict, you must have theirs and if you haven't tried but would be willing, you're not going to be disappointed. They make the hollandaise fresh for each order, the poached eggs are always perfect and the ham is thick and flavorful. On the drink side, their Strawberry Dream smoothie is a hit and their coffee drinks are wonderful! read more

Chicken pot pie wasn't to my taste. Ingredients were separating and it just not to my taste. Doesn't mean I won't come back and try the lox and bagel or the Rueben!! Cashier helpful but not over friendly. Still, will be back. My husband thoroughly enjoyed the Cuban. read more
