I've been up there a few times—the main venue for gigs is behind those curtains to the right, I think, where I last saw Thea Gilmore, which I think means that the little balcony is next to the cafe, though I don't recall there being an outside space there. I may just not have been paying attention. I've had lessons at the Folk House in all sorts of things, from film developing to songwriting, some of them in those top floor rooms (though the darkroom is in a cellar area accessed from the front courtyard.)
