First time here, won't be our last. We loved Grotto Grill and Fiesta Hill did a nice renovation and added a large patio with a grotto of Blessed Mary still there.

This restaurant has the absolute best food better than when I lived in San Diego, but I came in tonight not feeling like a margarita, I asked the bartender for something mixed with tequila, and she made me this wonderful tequila old fashioned, I ate the garnish and drank some so this is what’s left by the time I remembered to post good things!

Had a great lunch experience here last week with my wife and daughter. We shared the nachos and we each got a margarita and the bill was noticably low! Food was great and our server was funny and attentive. Will come back!

The food service in atmosphere are also amazing. If you know. Spanish it really helps because a lot of the staff is ESL. I The fried ice cream is very thick and. That's all sal's very delicious. This is a great place to visit and it looks like they've opened very recently or at least remodeled.

My very first time eating here and everything was absolutely delicious! Super flavorful, priced right, great decor, and good portions. I will be back! The only thing I wish they had was a Chimichurri sauce on the menu!!!

Great mexican restaurant super clean. Very fresh. Fast service and the server kept our drinks filled. We had 4 different meals from the lunch menu and we were all happy with the portion size and taste. The salsa was fresh and mild, not spicy. Overall a great place to eat, highly recommend.
