We sat in the upstairs area with reserved booths. I understand the desired vibe of the space, but it was just too, too dark to really appreciate or enjoy our food. That being said, the queso with chorizo, and the guacamole with crab and corn were both delicious appetizers. The tacos we ordered were fine (a daily special with barbacoa, the Tako taco with octopus, and the chorizo taco with a fried egg on top). The drinks were good. The chocolate dessert was pretty terrible -- dry puff pastry with ganache, garnished with the smallest dollop of chocolate ice cream. The service was a tad hit or miss -- our waitress disappeared for long periods of time, but the only downside was for the restaurant -- I would have ordered another margarita. Would I return? We won't rush back. But we'll probably come back at some point simply because there are not enough good Mexican restaurants in Pittsburgh, and this one is certainly pretty good. Next time, we'll sit in the bar area which seems to have much more light.
