Mario's Donut Restaurant

The BEST breakfast sandwich I have had in a very very long time! The quality was out of this world. The bagel was soft, fresh and chewy, thick bacon and great eggs. The cinnamon bun was so very fluffy and light. A welcoming family atmosphere! A great place that brings yoi back to a time where families sat down for meals and quality mattered. A new favorite restaurant for me!

Best donuts in St. Charles County and I've tried them all, locations that is. Local owner is putting out good food at reasonable prices. Cinnamon rolls are large and so yummy!!! Not just a breakfast stop, gyros are great, too! They have sandwiches as well. Really hate to share that their donuts are awesome because I know they will now run out before I get any. Location is just a quaint clean diner atmosphere, nothing fancy with people that care about what they prepare for you to enjoy. They are extremely friendly to do business with!!! Give them a try.

It's nice to see this place grow I haven't been here in years it's so much more fancy than before. Very good atmosphere. And food was great

The decor is kind of all over the place in an eclectic, endearing kind of way. I bring the kids almost every week and they love it here. The donuts are basic, but done well. The breakfast food is very diner-style, but the kids love it. Good family spot for a reasonably priced breakfast.

Mario’s has great donuts! Probably not the best we’ve ever had, but still delicious and most likely our new go to spot since it’s very close to home. My favorite of what we ordered was the cinnamon twist. It was very light, not too sweet, and had a good amount of cinnamon. The chocolate long Johns had chocolate that tasted a little darker than just plain milk chocolate but they were fresh out of the oven, so still warm and hit the spot.

The plain coffee is solid. It was really busy when we came in on a Saturday, but staff were quick and friendly. A friend ordered one of the breakfast sandwiches and said it was good, so we will back to try those next!

the baklava was one of the largest servings I've ever seen. Pickle fries were awesome and so are the donuts. Overall delicious food and really friendly staff. Place was clean despite being busy around noon on a Sunday.

Fun place! Good food! Came in for breakfast while in town for a funeral. Staff happy/friendly- everyone seemed like they enjoyed being an employee. Had a gyro breakfast sandwich on TT. Was really good- could have used more gyro meat as was give like two slices not even bread length- not worth complaining about. Got me thinking about how I could improve/have similar at home. Reports from my group is the donuts were really good. A few friends bought donuts for the rode. The scrambled eggs and avocado was reported good from the group. Very reasonable prices! Fun/relaxing atmosphere with some pretty cool paintings. Would have loved to sample a gyro as the meat was pretty tasty in the breakfast sammy. Good luck to your business! We hope you do well! TY for the experience!

One of the best local treasures. Every time I go here the food is delicious and the family style service is very appreciated. The chocolate long johns are the best first thing in the morning when the dough is hot and the chocolate is still dripping.

The staff on this day of 28th of July was ok they never smiled and didn’t seem to happy but for the food it is excellent I recommend the bacon egg and cheese on a everything bagel they are the whole reason I even come here and every single time I do the food is delicious. I give a A+ to the Cook‘s here and a C + for the staff at the counter

This place is easy to miss with an unassuming front in a smaller strip mall, but once you visit once you will never forget! Today was my first time grabbing some doughnuts for a work meeting. I was helped by a joyful, funny, happy woman that proceeded to hand select the most thoughtful dozen doughnuts anyone has ever picked. She gave me the rundown on the variety of this vast menu and just really went above and beyond to be engaged. The quality, portions, prices, and service all felt like we were absolutely in a time machine. I left with a HEAVY dozen doughnuts for less than I would have paid at a chain. As a salesperson I feel like I buy doughnuts every week, and I will absolutely go out of my way to make them Marco's. Cannot recommend this place enough.

Love this place! Husband and I went here for the first ,greeted by this nice young man,we even had a full conversation with him !. The gyros were so good, very flavourful. And my husband got a hamburger with 2 donuts as the bun he loved it as well! We will be back!

This is my favorite place in St. Charles. You can get a gyro, fries, a drink, and a doughnut for about $15. (2023) The restaurant is always decorated for different holidays. I love looking at the elvis portraits. There are also many lovely plants like Fiddle Leaf Fig and other house plants to enjoy while waiting for your food.

Came back to update my review. Gyros for lunch delicious! And then I was "talked into" a side of donuts! Thank you again. Nothing makes me happier than a true bakers dozen! 13 delicious donuts 🍩

Second time here and I’m convinced its not a fluke. This place rocks. Staff are friendly and the food is great. Gyros are excellent, the fries are excellent and the donuts and baklava is icing on the top. You’re missing out if you just get burgers and nuggets there are a lot of sleepers on the menu that I need to work my way through but I already know it’ll all be good. I’m Greek on my dads side so you can trust me. Worth every penny.

Mario’s has very quickly became one of my favorite places to eat! I stopped in a week ago for some breakfast and feta oregano dip, which I was impressed with. Today, I got the falafel and pickle fries- WOW!! I’m quite picky about falafel but they make it perfect! So happy to have found this place.

This was a perfect Gyro. It came out of the kitchen piping hot. The meat was very tasty and perfectly cooked and seasoned. I also had a side order of onion rings that were cooked just right. Definitely a go to spot if you’re looking for a gyro. Would highly recommend Mario’s.

This place is awsome.. great food and prices are reasonable!
The atmosphere is cool, love the plants, the kid corner, and all the little bites...

Before the owners changed they had the best fries after they sold it the fries were ok but now they are my favorite fries 10/10 would recommend

Fantastic little place for donuts. But also a really tasty all day menu too. We love the breakfast sandwiches and omelettes in addition to our favorite donut.

I went there for the first time today 09.14.2023... I had their sausage, egg, & cheese croissant which was really good. The corissant was very freah, flaky, & soft.. i also had a chocolate long john which too was very good & fresh too...
I would definitely go back.
