While visiting Phoenix, I decided to try Presidio Cocina Mexicana for dinner after reading the reviews. The restaurant is a nice, small, simple, local place. However, buyer beware! The prices listed on their online menu are significantly lower than the price you will actually pay. Bait and switch must be legal in Arizona.
Looking at the dinner menu, I was surprised at how expensive all of the entrées were considering this was a "hole-in-the-wall" type restaurant. I chose the chicken enchiladas for $18.95. (Their menu online lists the entrée as $10.95.) In addition to refried beans, rice, and a small salad, I got three, chicken enchiladas that were still cold in spots. Chips and salsa, while standard at most Mexican restaurants, apparently were extra at Presidio Cocina Mexicana. My total bill, including tax, for the enchilada entrée and a glass of water was over $20. In my opinion, it was overpriced.
Presidio Cocina Mexicana was nice to try once, but I wouldn't rush to go back there. I think there are better options.
