With a genuinely disgusting bathroom, a cash-only bar, and faux stone walls that haven’t been touched since 1972, most people would call Cantab Lounge a dive. Maybe it is, but this is Cambridge, so the dives here have weekly poetry slams. The drink selection is pretty basic and there’s no food (you can bring it in from outside,) but you’re coming here to have a sloppy good time with nightly live music.
