Don't remember ever drinking coffee there, but The Cellar Door in Washington, D. C., deserves mention. It was a cramped but cozy place to hear and see folks who were becoming and people who already had become well-known. Others, like me, were happy just to get a chance to get on stage now and again at the Sunday night Hootnanny. Ian and Sylvia had their own mailbox in the alley (which doubled as the backstage area). I missed seeing Bud and Travis play there but I remember seeing Joe and Eddy's performance. They were backed by an excellent bassist named, Buck Wheat. Another D. C. coffeehouse of repute was The Crow's Toe (it featured a stuffed crow suspended from the ceiling by that appendage).
