Been there once a while ago, but it left me a decent impression. Although it is not the best wine place I have been to, it is pretty decent for Pittsburgh.
I haven't found many wine bar here in Pittsburgh like I did back in Cleveland. But this one has the feel I look for - dim lighting, candied bacon, etc.
The environment is on the loud side, so if you are looking for quiet and intimate environment, I would not recommend this place.
But if you are going to just try some fun chocolate and wine, it is worth stopping by at some point to give it a try!
