Probably not a secret for locals but if you like wacky and fun, try Bar 11 in the south side. The address is 1101 Bradish, Pittsburgh. They have quirky stuff like a beer vending machine. Beer is $2.50 / can, only takes dollar bills but doesn’t give change. Random, weird stuff all the time. Just a fun place for all legal ages. Full disclosure, I do not have association with the place nor do I live in Pittsburgh.
