This place exudes cool. Glass encloses the kitchen. The dining area is dim, with octopus on the walls and red light fixtures dangling from the ceiling. Our uber-hipster waitress explained that tako was Japanese for octopus.
Three of us ordered different tacos. The winner was the chorizo taco, with the fried egg on top. I didn't care for the Korean taco; it was way too sweet. On the other hand the choco taco, a desert, wasn't sweet enough. There's something off with that.
The tacos are expensive by Texas standards. Similar tacos at Austin's Torchy's Tacos, or Velvet Taco in Dallas, run about half as much. Even the tableside guacamole at Boudro's on San Antonio's Riverwalk is 50% cheaper than it is here. But there don't seem to be any other fusion taco places around, so I imagine it's OK for Pittsburgh. I'd try it again at least once.
