Yesterday I visited the Wilhelm Bauer in Bremerhaven. Unfortunately it was still closed though so you couldn't go inside the sub, but there was also the schifffahrtmuseum to visit and the weather was pretty good.
Some things to mention when you guys are planning to go over there:
Dont visit the mediterana complex, it's sort of a big shopping mall with some restaurants. Waste of time to go inside, it's great for the wife (and kids maybe), don't give her too much money too spend

. Sitting outside drinking a couple beers isn't a bad idea at all though.
The restaurant inside the schifffahrt is the place to go to. It's called 'panorama cafe weserblick'', it's really very nice.
Alright some pics, more to follow:
