If you don’t try this café, you’re really missing out Food is excellent. Service is excellent. Owner is so nice. I will be going there quite often. Go check it out.
I ate there recently for lunch and LOVED it. food and drinks were delicious. service was great. Cute place. Prices were reasonable. I'll be back!
Great spot! It’s hard to find Mexican breakfast around here, so I was really glad to see it on the menu. I had the breakfast tacos and they were amazing everything tasted homemade. Excellent service and a nice little place overall.
A ‘must go to’ place for breakfast. My son said ‘breakfast was fantastic and definitely brag worthy’. Reasonably priced, clean and service was great. Telling all our friends and we will be back.
My wife and I took are little girl here for her 4th birthday. They treated us like family and put a big smile on my daughter's face. My wife had the Turkey Club, I had the Torta, and she had the MacNCheese. It was amazing! I highly recommend.
LOCAL PEOPLE: Do NOT sleep on this place! Amazing food, amazing prices and amazing staff! Who doesn’t want a Sunrise Special and a mimosa to start the weekend! Highly recommend!
First of all, hands down, some of the best food I’ve ever had. It’s a small place, which I love. I got a lime margarita and started off with chorizo dip. AMAZING. I had left over dip and used it with the Heuvos con chorizo and I think I literally saw a light come down from the heavens. It’s at least been a year since I had such a reaction to any food. Please eat here and kiss your server on the forehead. ***Unsolicited kissing of foreheads may lead to charges being pressed, proceed with caution
We LOVE Mario’s- Mario makes the best environment, food and margaritas! Breakfast, lunch and dinner - all fantastic. If you haven’t gone to Mario’s yet… you should! :) Mario is exactly the kind of person that should be in the restaurant business - loves his customers and his community
It was my friend and I 's 1st time here. We always try to go to a new breakfast place each time we get together and everything was top notch. We definitely will be back. It is a great place to meet up with friends or family members. I can't wait to bring my family. Mario and Yanet really make you feel welcomed.
Had a great breakfast here. Sat on the patio had pancakes and home fries. The pancakes were light, fluffy, golden brown and delicious. The home fries were crispy, but could have used more seasoning. Coffe was also good, server was attentive and friendly. Not sure if cash is accepted 🤔 . Bill was on hand held device that server dropped off. Will be back!
