This genuine Irish pub has doubled as a bohemian oasis for 40 steady years. There's Guinness and Bass on tap, many Irish whiskeys, and light rock, Irish, or country music nearly nightly. Narrow and cozy, the Plough is a comfy, noisy place, a den for locals and students, but a fine place to have lunch alone. The cover charge varies. Fun fact: literary magazine Ploughshares was founded here.
