Yeah, there's a pirate ship in there. I found an old newspaper from 1969 that had an ad for the Piccadilly restaurant at that same address. It said you could dine aboard the HMS Bounty. So i assume the boat was there back then and you could eat in it. I heard one time Marilyn Manson partied in there.
It's a real dump, but you usually don't have to pay to get in, so it's a cheap dance club. The crowd is goth/indie and not a bunch of assholes. Sometimes they have concerts here.
Urban legend: someone pushed Trent Reznor down the stairs either here or at the Chamber. Some dbags claim to have done the deed. I don't know. It is the 20th anniversary of Pretty Hate Machine which he recorded in Cleve. Maybe they'll have a party for it?
