Service - very friendly; order & pay at front, grab a number and they bring to you.
Venue - Not a huge amount of seating. We arrived on Saturday around 12:30 so it was empty, but by 1:30 it was full.
Food - Got the Veg tamale. It's very large, but unfortunately it was very dry, and for some reason the veg tamale just seemed to have beans in it (beans are not a vegetable...). Tried to moisten it with the salsa, but the complimentary salsa is the amount you get in those McDonalds ketchup cups.
However my friend did say the fish taco was one of the best she had in the city, but mentioned the beef was kind of bland.
Value - great, prices are generally cheaper than most Mexican places in the city.
