When you enter the bar, you’ll receive a Seaman's Book (or Seefahrtsbuch) before you can take part in the Polar Expedition. The Seaman's Book documents you as a crew member of the Hansa. It also documents the drinks you have consumed, so be sure to have it stamped when you order your included free drinks in Berlin Icebar (one in the tavern and two in the icebar).

Drinks in the tavern

You enter the Polar Expedition in the tavern. A nice, warm bar where our bartenders are ready to pour you a drink while you meet your fellow crew members.

Drinks inside the actual Icebar

As you brave the cold of the Arctic, you can claim your two included drinks at the icebar.
