Now open at 12242 Rockville Pike: Bambū Cafe, a sleek-looking snack shop in the strip center that once was home to Chef Geoff’s and Five Guys. The restaurant offers a Vietnamese-inspired menu of sweet coffees, bean-based chè drinks, fruit smoothies and bánh mì sandwiches. A couple of doors down, the Nature Kitchen restaurant that was supposed to open this summer is no longer happening. Its space has been filled by quick-serve Japanese eatery Katsu Go.
