"When the Fairmont Copley Plaza Hotel decided to shutter its iconic Oak Room in 2012 and revive it as OAK, a more contemporary bar, the area's staunchest traditionalists were skeptical. But ever since its reopening, this urbane hot spot has become a seamless part of the Back Bay bar scene. The cocktail list is cheeky, with fun options like the "How Do You Do?", a mix of Grey Goose, St. Germain, Aperol, and grapefruit. There are a couple of local brews on tap, as well, plus a nice selection of whiskey and Scotch. There's always a great energy here, especially in the warmer months on the patio overlooking Copley Square." - Todd Plummer
