I'm going to be in Hamburg for a couple of days next week and there's been a dearth of threads about what to do there, so far all I've got is the world's largest model railway. http://www.miniatur-wunderland.com/

So, things to do? food places? drink places?

You can also tell me about Copenhagen and Berlin if you want but there's a load of threads about them. Maybe there are new things since the last thread?
