The restaurant and the food is good. Nothing spectacular or entirely different or new, but that is okay with me. (Also, this could be due to the dishes that I order, as they have things on their menu I have yet to see at other Mexican restaurants).
I ate here about 5 times now over about 3 years. The quality of the food has never changed. I usually order the enchiladas Aztecas which is 3 enchiladas with 3 different sauces. This also come with a plate of re fried beans and rice. Priced at about $10.75 - $11.99 (can't remember, but not $12). There is nothing that I don't like and always leave full and satisfied.
The atmosphere is calm and average, and I never felt like the place was unclean. The bar tender has always been friendly to everyone walking in and out of their door.
On Mondays and Wednesdays during happy hour they serve $3.75 margaritas, which to me is a deal! During this time they also have food deals.
Concina Mendoza is usually not my first choice of where to eat, but once I am there I am pleased with the service, the food, and I always leave wanting to try more.
