Popular for office happy hours, this downtown DC Irish pub draws a crowd most weeknights. Young professionals grab a stool at the long wooden bar or squeeze into one of the hidden-away booths for $2.75 and $3.50 beers Monday through Friday from 4 to 7. The back room is large and inviting with a mishmash of wooden tables and leather armchairs, brick walls, and a fireplace. In warm weather, the patio is often packed.
