El Azteca - Fine Mexican Cuisine
i didn't know any better until i took my gf there. when she asked for horchata and was told that they don't have it, she knew they weren't legit. she pointed out several other things throughout the meal. my gf is from sonora, so that's the style she was comparing it to.
all that being said, the food is good, just not authentic mexican. we've never come across an authentic mexican restaurant that didn't serve horchata in addition to other types of agua frescas, and never came across one in hoard county.
the city i live in is 80% latino
