Blauer Peter (blue peter) is a phrase from seaman’s language. It comes from the blue-white signal flag, which means the ship sets sail in the next 24 hours and lets the seamen on their shore leave know they have to come back to the ship and let the local pubs know they needed to make out their invoices. The Blauer Peter (meanwhile number IV) has a long pub tradition in the Kiez (Reeperbahn-area) in Hamburg.
It’s a good start for a Kiez-tour. Prices are cheap (Astra beer for € 1.60), they have rock and punk music, sometimes a DJ, but this is not a place to listen to high-quality music. The staff is monosyllabic, but quaint. The pub is raunchy and uncomfortable, but a nice place to go after a FC Sankt Pauli soccer game. Oh, and by the way, officially over 18 years only! It was the first pub in Hamburg I saw.
PS: Forget the toilets – naaaaasty!
