In the page's words:

Every Wednesday from 18:00 to 24:00, we host the iconic Seehaus Afterwork Club: Right on the water on our jetties, at the Sailor Bar and on our large terrace there is ELECTRIC MUSIC from DJs - plus champagne, fish & sushi.

Just a 5-minute walk from the heart of St. Georg and Uhlenhorst, only a 10-minute walk from the main train station and the city center, and "right in the middle" between the boats on the Alster and the Alster hiking trail!
