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!

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.
