I just got PM'ed about this. I am not 100% in as I have to attend a wedding the next day outside Hamburg.
Two places to recommend are Au Quai (kinda snobby but good food plus they have a 'lounge') and Le Lion (cocktail bar, highly recommended although I've never been there). Au Quai is close to Indochine.

Depending on if/how I make it I might be able to pick up people on the way ... if I take my car.
