The Trinken Cart is located outside on the promenade across from the rest of the Germany Pavilion.
It serves the same pretzels as Sommerfest along with some interesting beer choices. This is the best place to pick up the Schofferhofer because it’s on draft with usually short lines. The Erdinger Dunkel is in a bottle and very good, though it’s awfully expensive here.
