New restaurant opening this weekend at Rockville Town Square: Friendship BBQ, on Maryland Avenue next to Color Me Mine. The fast-casual Asian eatery offers skewered meats and seafood cooked with wood imported from the Xinjiang region of China. Just around the corner, three more Asian restaurants will be opening soon inside the former Mellow Mushroom space. Meanwhile, there won’t be any burgers at the Square for a bit: Five Guys is temporarily closed for renovation.
