Mexican cuisine is one of our absolute favorites, and we were blown away by the authentic flavors and warm, inviting atmosphere. This was easily one of the best places we ate at during our trip to the Grand Canyon. What we ordered: 1. Kids: Chicken tacos meal (huge hit with the boys!). 2. To Share: Steak fajitas, a fish taco, and the Nachos Supreme. The fish taco was huge and packed with flavor. The fajitas were also a massive portion--the steak was cooked to perfection, making it perfect for sharing. My husband's only minor complaint was that the nachos used a cheese sauce/Whiz style cheese rather than melted shredded cheese, but they were still tasty. To top it off, the horchata was fresh and full of flavor, and the colorful Mexican-themed decor added so much charm. Highly recommend stopping here--we will definitely be back whenever we're in the area!

We made that mistake in Boston - shudder,cringe.) Nanys looked like a great family- run place and it did not disappoint. Right off Route 66, it's cozy and colorful. I stuck with a basic bean and cheese burrito but it tasted perfect to me. Like a lot of places now we had to pay extra for chips and salsa which I don't love. Fortunately these were good so it was worth it. My husband had the green chili pork and an el pastor taco and enjoyed both. He balances out my boring orders. We were very happy we found Nanys.

The chips are home made and we wished we could have bought a bag. The chicken mole is a HALF of a chicken! We all took food away and ate if for dinner the next night. Total value throughout.

The restaurant is huge but they didn't have enough staff that day so there were a lot of tables that needed bussing/cleaning. There were a few large parties too.

The food wasn't anything to write home about but the staff was very nice even though they seemed overwhelmed. They did apologize for the wait. We had a lovely meal. The loaded fries were delicious.

There are two options for the Birria pizza, a 10' and a 14', the 10' serves 2 people and the 14' serves 4. $10 difference between the options. Each person gets their own dip and it was absolutely mouth watering!!!! My parents shared the steak fajitas and couldn't stop raving about how juicy and tender the meat was! They also really enjoyed the bell peppers. Might come back for dinner tonight.

The food was fresh and hot. I got the chicken street tacos, which were tasty and not spicy. Perfect for me. They were really orange and I spent my entire meal trying to figure out what made them so orange that color. . My husband got the Pastor tacos. His comment was there were so many spices, he could hardly taste the Pastor portion of the tacos.. He tried my chicken tacos and thought they actually would've been a better choice for him. The Waitt staff was OK. Nothing to write home about but nothing wrong. The ambience of the place was like a regular Taqueria. So I'm giving it three stars because it's average. It was fine and if you're looking for Mexican food, you can go in and give it a whirl. But I wouldn't suggest you stop off in Williams just to try it out. But if you're there, and you're hungry for Mexican food, you can give it a try.
