I have eaten here three times so far over the last month or two, and it has been consistently great. There are a number of places in Pittsburgh to get Banh Mi/Vietnamese food, so one definitely has options. I have been choosing this place as my option because it is just all around a good experience.
The top things I would recommend off the menu are the Banh Mi (obviously), the tacos, and the Pho bone broth. When I ate here last Friday I had the tacos with pulled pork, and it was fantastic. I plan to try the noodles next time I go back.
Also incidentally, this place is located within Smallman Galley, for anyone who is not familiar. They have a bar there which is a great place to get a drink, either before or after you eat. As I said previously, I was there last Friday night, and it had a nice crowd. Most people were, similarly to me, at the bar to have a drink after eating at Banhmilicious.
