OK, so here's a restaurant I've found in Hamburg which looks FUN!!! (Heehee!!!)
Restaurant: Kartoffel Keller, Deichstraße 21 Hamburg 20459
As this restaurant is only a few stops away from the venue by underground, we think 17:30 is an ok time to meet there.Let me know if you're in, so I can make a booking online.
[OR, if you have an alternative sugeestions re restaurants or time, please provide website details of the restaurant. We do not know Hamburg at all
