Bac is a wonderful addition to Tremont's culinary scene. Bac Nguyen is doing some really great things with Asian fusion food. One of the most comfortable patios to eat on in the neighborhood, their portion sizes are appropriate, their menu isn't static and their bartenders make excellent and unique cocktails. I've eaten there twice and I can't NOT order the bacon guacamole, it's so good. I've also had chorize spring rolls, the bahn mi and several noodle dishes. All of which were well above par. Bac is one of my favorite places to take dates and just really one of my favorite restaurants in general.
