Disco Cassero
Via Don Giovanni Minzoni 18, Bologna
Disco Cassero is run by Bologna's LGBT center and holds parties on certain Saturdays, plus the occasional night on other days of the week. The big vaulted basement makes it a striking place to visit in its own right. Things usually stay quiet until around 01:00, after which a long line at the door is common. Entry requires an Arcigay membership card, which you can buy when you arrive.
