I'm not in the great state of Maine any longer, but if you're in Portland on a Sunday afternoon you MUST get yourself to Brian Boru's on Center Street. Back when I was up there they did $3 pints of Guinness, Bass and Harp Suday afternoons and excellent live music. "Push the benches against the walls and break out the fiddles and pipes" type live music. Raise a pint or three of the black stuff for me if you go!
