This place needs like 5 separate reviews. I mean, it's a bar area + 4 chefs, so I really do not know how you share the review along them. All stores (except the bar) share the same sitting area, so it certainly has college / food court type of feel.
We had a burger with the one furthest inside (enter from 21st St). The burger is certainly 5 stars. It has mushrooms and the sauce was special. One of the best I had in the Burgh.
We had an octopus salad too (second last store from 21st St?!). It was "special-but-ok" / "alright, that's interesting". Not saying it is bad, not at all, more like "Mmm... O.K.". The portion was definitely on the small scale.
Will be back for the burger, but not sure about the octopus salad. Did not try the other two places yet, but the seared scallops from 2nd store in looks delicious.
