Prometheus Tanzcafé is quite a big place in the old town and almost exactly opposite of the "Golden Roof." But beware, it's not quite as posh a spot as you might expect from the location. It calls itself a "Rock Café," and the lovers of music that come here, tend to treat themselves to a glass of beer or two - after all, it's the thing that goes best with rock music. The cellar bar in particular is quite a noisy place, with a fairly idiosyncratic atmosphere, based on its dark stone walls, dim lights and seductively comfortable sofas. Up the stairs, there's the cafe, part of the establishment, where everything's much more quiet.
