When I first visited HafenBahnhof I was living in St Pauli and quite new to Hamburg - it felt like…read morea very long trip to get there and back. I haven't been back in a long time, but with my now much-more-substantial knowledge of Hamburg, it doesn't feel so far away - especially if you happen to live in Altona or own a bike (cycling around Hamburg is easy).
The bar itself is sort of like a big shed (see the photos). They have a small stage at one end for bands, which is actually the only reason that I've ever visited!
