Boston brunchers know that the South End is the place to be every Sunday morning, but the classic tastes of the Buttery often top neighborhood favorite lists for lunch and dinner, too. Enter through the destination-worthy bakery and coffee shop, and descend into the grotto-like subterranean dining room, where cozy banquettes and colorful bud vases decorate the fireplace-warmed space. The continental menu is small but sufficient, with options that range from braised beef cheeks and eggplant parmigiana to house-made veggie burgers. Be sure to order a side of fries—they are some of the city’s best.
