I've been here a few times. I'm mainly posting here because I figured I should write down the address, as Google Maps can't find it. It's at 780 Somerset W. (Very close to the Booth / Somerset intersection.)
I got a shredded pork sub today and thought it was a little dry compared to most banh mi I've tried. I don't think they put any butter or pate on the baguette like they do at some other shops. For $2, I can't complain though. I'll try their banh mi thit next time, which has cold cuts instead of the shredded pork.
