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!!

Best restaurant in Williams!

My husband and I stopped in here for a quick bite and we were seated immediately and had a wonderful waitress. I had a cheese enchilada and Chile Riano, and both were delicious. I am really picky about my chili. Renos, and this one was done perfectly. Very authentic place and I highly recommend.

Very friendly waiters! Steak was very good, guacamole was fresh, and the atmosphere was very welcoming. 10/10 would recommend.

This is a great place to come for a delicious meal brought to you by a dedicated family. The flavors in the food blend well for a satisfying experience. It brought back childhood memories growing up in Texas with Tex-Mex style food. This is a little different style and just as wonderful.

Came to Williams to enjoy the weekend. It was so cold and it’s cute small town with a lot of tourist shops and food places. We decided to stop at Fiesta Mexican Grill because it SMELLED amazing! It also had the whole menu plastered on the windows so it was easy to see what we want to eat and see the prices. Once we got inside and sat a table it was nice and cozy. We were served chips and salsa and received our drinks. Try the horchata (homemade)! I got the chicken enchiladas and it was filling. As you see in the picture, my friend got the “super” burrito! It’s big enough to literally feed 4 people. I would definitely stop by for some food next time I’m in Williams.

I will give it a 4 stars for the beautiful price and delicious food! We asked 2 local people from the shops they both said if you like Mexican food this is a good local Mexican food restaurant. We walked around the town and decided to go here. The food was beyond my expectations, the tacos were really good! Fresh lettuce and tomato , family friendly service, excellent price!

Went here late one evening by myself. It was one of the greatest restaurant experiences I have ever had. The family who owns and runs this place is incredible and so kind. I would highly recommend and will go back as soon as I make it back out west. Food was great, atmosphere was great, and the tres leches cake that topped it all off was perfect!

Me and my family were on vacation and we decided to eat at this restaurant. We ordered 3 fajitas and 1 burrito, which came out to be 80 dollars. Unfortunately the food was bland and we ended up getting food poisoning. It pretty much ruined the rest of our trip. I was shocked because this restaurant has good review but I definitely would never eat here again.
