After hours, Boston [1] has a rambunctious mix of old-time Irish bars, dance clubs, and newer upscale lounges. As a remnant of the blue laws, “happy hour” drink specials are forbidden here—though many bars offer free food for the after-work crowd. Smoking is also illegal in all bars, though a few may quietly let you light up in back.
Bars in Boston and Somerville [2] generally close at 1 a.m. during the week and 2 a.m. on weekends. Cambridge [2] bars close at 1 a.m. nightly.
