Poor hippies. Mill Avenue used to be a place where patchouli and sage were always in the air and the irie goodwill ran wild. Now, it would be a miracle to find so much as a drum circle that wasn't broken up by the cops in five minutes. Fortunately for the city's disgruntled Deadheads, dread heads, parrot heads and maybe even a few redheads, there's the Sail Inn. This place has taken its nautical theme and run with it. The main dining area has shiplike wood paneling and a Day-Glo aquarium mural decorating the wall behind the stage. There's Phish on the jukebox and $5 beer in generous-size pitchers. And the live music that ranges from bluegrass to reggae to Grateful Dead covers to a sorta Middle Eastern-influenced group called Maruma is perfect for dancing in long twirly skirts or shaking dreadlocks to the beat.
