★★★★☆ 4.0 Jonyi Herrera · Dec 2025

This is our fourth or fifth time going there for breakfast or lunch. It's a place with a great atmosphere to enjoy your meal. Mario, the owner, is very friendly, and the waitress, Janeth, does a great job. We go back whenever we have the chance, for the chilaquiles, the birria tacos, and the street tacos. Today we tried the molcajete, which was delicious. I highly recommend it. Okay, this is my second review after two months, and it's about the margaritas. I'm not a huge margarita fan, but the peach margarita I ordered with a chamoy rim and Tajín seasoning was really good. By the way, this picture I just posted is of my second drink. I highly recommend this place.

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.

Went for breakfast this morning (Sunday) and had a great experience! Pancakes were delicious, sausage gravy was flavorful. Service was great. We will definitely be back!

I NEVER post reviews, so that should tell you something YEAH, NO…….I kept looking around because I thought I was on candid camera…..THERES JUST NO WAY!!! The chicken and waffle is LITERALLY just a warmed up chicken strip cut into 3 pieces🙄 not even crispy… breakfast tacos SUPER DRY and pasty with a block of cheese plopped on top🫣 the 2 egg breakfast…JUST FORGET ABOUT IT….they don’t have to worry about me again….

★★★★★ 5.0 Ricardo Carpio González · Feb 2026

This place is a total gem! The chilaquiles are easily the standout dish; they have a unique preparation that sets them apart from every other Mexican spot in the area. Between the perfect texture and the authentic flavors, it's a must-try for anyone looking for a great brunch.
