Wow! We were visiting from out of town and came here for lunch. We really enjoyed the Street tacos as well as the chips and salsa. Everything tasted authentic and was served fresh and hot. The service here was wonderful and we even met the owner's son who shared a little bit about their business. We love supporting small and local while traveling, and we will definitely be back when we are in town again. read more

A Mexican diner. That means only not overly large menu you can get a few standard Mexican dishes, but also choose from American breakfast classics -- and even toasted ravioli as a nod to St. Louis cuisine. Everything is available as long as Mario's is open. Our party of four was impressed when the owner came over to check on our meals and talk with us, and then several minutes later remembered and thanked each of us by name as we exited. read more

Mario’s Cafe - It's a small spot. - Breakfast & Brunch Near Me - O'Fallon, Missouri

Just went for Dinner last week 10/10 and had to bring my wife for breakfast/brunch. Started with a Marg and a Modelo- what else we have!! Again, everything was top quality with just the right amount of Heat! Red sauce/green sauce on the Huevos Divorciados accented the easy fried eggs and pan-fried (rather than oil fried) home fries. My wife had the Breakfast Tacos and subbed the chorizo for ham. Fresh tortillas were perfect. Loved it! And for our sweetness we had the Strawberry Cheesecake French Toast. Not overly sweet with the fantastic whipped cream cheese filling. It was like a mascarpone but very creamy! No need for any syrup. Don't miss this item! read more

Was crushing the streets and found Mario's Cafe. Located on Main Street in O Fallon, Mario's is a fresh spot to enjoy breakfast or lunch. We stopped by on a Sunday morning and saw a very busy cafe. We were seated without any issues and was welcomed by Mario the owner and our server. Very friendly staff and provided the specials for the day. Mario's has both traditional breakfast options as well as a Hispanic options. We went with Mexican breakfast and was impressed with the authenticity of the dishes. Prices were reasonable and service was great. I do recommend trying the Mexican breakfast options as there aren't many restaurants serving Latin cuisine in the mornings. Highly recommend and will be back!! read more

Great small business. Visited for breakfast. Service with a smile. It's a quaint space so not ideal for extremely large group. Breakfast tacos were amazing. read more

This was our second visit for breakfast and it didn't disappoint. I like to start my day with savory, my husband likes sweet. I ordered the Chilaquiles, he ordered the Pancake breakfast. What is that sweet, almost tart flavor of their pancakes....they are hard to resist! But my Chilaquiles plate of crispy tortilla chips with green chili sauce (I added some of their red sauce too!), lots of tasty pulled chicken, the perfectly fried eggs, sour cream, lots of sliced ripe avocado and the queso fresco was creamy, rich, generous and very filling. The chili sauce (both the green and red) is mild but has a nice fresh flavor. No regrets about my choice. I wouldn't be afraid of a little more heat from the chilies, though. Service was friendly and welcoming. We were greeted with smiles. Can't wait to return, thanks for a lovely breakfast. read more

Small but mighty! This little place is a gem! Mario owns another amazing restaurant in OFallon so we had to check out his new cafe. Food and service were top notch! It's a cute little place nestled in OFallon off of Main Street. They have a full bar and menu that is all served all day, even pancakes! The cuisine is Mexican and American-small menu with plenty of goodies to choose from. Stop in and give this new local business some love, you won't be sorry! read more

Breakfast food was good. The hash browns had a seasoning in them you would expect on fries which tasted good. I would go back. read more

Can't say enough amazing things. What really makes this place special is the owner Mario. He really takes the time to get to know his guest and make them feel welcomed and at home. I have been going to his other restaurant in Ofallon Dos Primos and it's equally as amazing! read more

I seriously cannot stop boasting about how much I love this place! I've tried multiple items on the menu and have never been disappointed. The food is delicious, flavorful, and generously portioned. Every employee I've interacted with has always been so kind and always smiling and laughing with regular customers. The dining area is a bit small, it's comfortable and cozy! Don't think twice about going, just do it! read more

Incredible service and the food was amazing! Food came out super fast and the people were so kind and helpful. Look forward to visiting again. read more

Stumbled upon Mario's and wow, we were blown away. Definitely what this area is missing. We had the breakfast tacos and loved every bite. Owner was super personalizable and lovely. 10/10! Selfishly I just hope it doesn't become too crowded once word gets out because the place is small! read more

Excellent food, service and drinks. Open ALL day so you can enjoy breakfast, lunch or dinner. Menu has many options. Outdoor patio is an added plus! read more

You can't go wrong with Mario's! Breakfast or dinner, whatever you get is going to taste great! Staff is friendly and fast. Clean establishment. Mario makes you feel like family! read more

We visited Mario's Cafe for the first time this morning and ordered breakfast. The service was awesome. The coffee was strong, just how I like it. We had the breakfast tacos, loaded home fries, pancake & sausage breakfast plate, and the strawberry cream cheese French toast. Every single dish was absolutely delicious. My favorite were the breakfast tacos but I tried the pancakes and they were so good I might have to get those next time. They were crispy edges and perfectly sweet. The hash browns were made to order (extra crispy) and actually seasoned! Most restaurants severely under season their food but Mario's cafe was so good. We will definitely be back and would recommend you try it too. read more

Great food and service, the homemade gravy is as good as you will find anywhere. We have yet to try a dish and be disappointed. From any of their breakfast plates to their tortas and tacos. If you don't like something about the environment, service, or food, I would look within because there isn't much to complain about at this place. Try it and you will agree IMHO of course. read more

Love the breakfast hash browns . The donuts are delicious! Pretty good chicken gyros too.

Fantastic authentic Mexican restaurant. Do not hesitate to go. But be careful to order the jalapeños, cause they bring the heat at Mario's!

Best cafe around! Great breakfast! The chilaquiles is amazing! Very Cute patio! and they have drinks!

Our first time at Mario's Cafe! We sat on the patio and it was so welcoming! Ordered each a frozen line Margarita and the ordered cheese and chips, which was so yummy! Then we ordered our dinner which we both got three tacos, some with corn tortillas and some with flour. Both came with black beans. The evening was very nice with the sunset! They are open for breakfast and lunch and dinner!! If you haven't been yet, please check them out, you will not be disappointed! We met the owner and some family, also named Mario! Check it out! read more
