I met a friend here for lunch on a recent trip. The place doesn't open 'til 11:30 am but they were totally fine with letting me in at 11:15 and having a glass of water until my friend arrived.
I'm from Phoenix (Mexican food mecca) and mostly a vegetarian. The tacos looked good but most of them contain meat. I also have a palette of a 5 year-old so I'm not interested in excessively fancy food. I ordered off menu and asked for a bean/cheese/rice burrito and they were happy to make it for me. My meal was good - great value for the price - but not OMG I have to eat here every time I'm in town! (Then again, I have the palette of a 5 year-old.)
My friend had the street tacos and they looked really good. And the staff was great about keeping our water glasses filled - and thank good for that because it was a warm humid day.
