This is the same restaurant as http://www.yelp.com/biz/carbajals-mexican-food-mesa-2.
I visited Carbajal's on a Friday night. They seemed to have a loyal clientele of regulars. The prices are a little steep like Mi Amigo's. The food is hearty AZ Mexican food, though not as good, I think, as Mi Amigo's. I ordered a Chile Relleno and Enchilada combo, and I enjoyed it enough.
I thought the decor detracted from the experience, and the boxy feel of the space was uninviting. I liked the Mexican music playing on the sound system.
Service was fast. My payment was completed before I was done eating.
