Friday and Saturday night after 9 or 10 p.m. should both be good. You could be a little ahead of the night crowd at that time. I was at Steamworks the last two Saturday afternoons and left before 8 p.m. The afternoons had a decent crowd -- of course, the first Saturday I was there was Pride Weekend -- but I noticed that it got dead after 6 p.m. It should have picked up later in the night, but I couldn't stay around that long. Besides, I found plenty of tops in the afternoon to satisfy me.
