On a quiet corner in South Boston in a dining room the size of a postage stamp, Chef Shi Mei offers an experience that’s about as intimate as they come. You will not find a fleet of servers, expensive plates and cutlery, or lavish decorations. This is not the place for pampering. What you will find is a chef who openly engages customers and cooks with a refined casualness that often takes you by surprise. Both the meat and vegetarian tasting menus yield a handful of courses that do not hew to one particular region or cuisine. Highlights like scallop crudo with rose, rutabaga soup with truffle, and parsnip panna cotta change with the seasons. Bring your own wine, share glasses with a nearby table, and enjoy the night on your own terms.
