I haven't been to many tapas bars, so I can't give too deep of a review comparing it to others, so take my enthusiasm with a grain of salt in that regard, but I will say that my fiancee and I LOVED Soul. Every item we tried was superb and the choices let us explore a variety of tastes.
The atmosphere is very dark and cozy, as you'll often be mere feet away from the diners around you. However the servers are very attentive and tended to any need we had. Try the Asian Glazed Pork Belly Tacos. They are AMAZING and unlike anything we had tried before.
