Located in Chinatown, Boston at 15 Hudson St, Boston, MA 02111, Great Barbecue offers traditional Cantonese barbecue meats. In my opinion, this is a hidden gem as only locals eats here.
Their menu can be found at https://www.bostongreatbarbecue.com/bbq_menu.html. While the menu is not vast, it makes up in its quality. When I go, I always get the 3 meats on rice for $10 (could have changed since I went). The meats that I get are Roast Duck, Char Shao, and Soy Sauce Chicken. If you decide to go make sure to have cash as they are a cash only establishment.
