I know there is a hookah shop in Adams Morgan (DC) across the street adn up a few store fronts from Madams Organ. I was down there a week ago and passed by. I wanted to go in but was with some co-workers. I think its actually a hookah restaurant of sorts, there were people sitting outside at cafe tables smoking flavored tobacco from some pretty elegant pieces. Anyone know the name of the place I'm thinking of? Odds are if they have hookahs they have pipes.
