Fantastic little gem of a restaurant we found by chance. They didn't have any vegan options but were more than happy to just remove some ingredients to accommodate us. Portion sizes were also really generous, we rolled out of there. Staff were so warm and inviting, great vibes.

Traveling from Southern California and passing through we decided to eat at this spot and it did not disappoint. It was delicious! The server was very sweet as well and was on top of serving us chips and salsa. I ordered the shredded chicken burrito with rice and beans . The food filled me up till the next day. Thanks again!

This was the best food I have ever eaten. Everything everyone in our group had was the best Mexican dish ever. Was it a little warm inside? Yes, but don't let that deter you!! They have the best guacamole and chile rellano. Enchiladas are top notch and every taco they have is amazing. Everything is amazing. We found our new must stop place in Williams!!

My wife and I had a very nice time here. The fajitas, chili relleno, and margarita were all great. I saw some other reviews on here from years ago that mentioned a pest problem, we looked around and walked the entire place, we saw none of it. If mex is what you are looking for, give it a try. Cheers

First time trip to Williams. Tried this place with the family. Great to see family-run; especially with the kids helping out. Outstanding food, and even better service. One of the best Cadillac margaritas I’ve had in a long time. Shrimp tacos, combo fajitas, and bean burritos were amazing. Highly recommend this restaurant.

Best restaurant in Williams! Seriously. They knocked it out of the park. And the prices are great for this little tourist town. Salsa? Good! Pork Carnitas tacos? Good! Enchiladas? Good! Even the sour cream tastes better than most (maybe homemade?) Great service and fun cantina vibe. We will be back!
