Paulaner or octoberfest
Don't buy a Bud here!! Paulaner Beer is Good! The Oktoberfest is their best seller. Also be sure to try the "Liquid Bread" beer.
Expensive beer, but what else are you going to while waiting for a train?
Bartenders are very nice, and will suggest or create something if you're not sure what you want.
Not as crowded as it looks as long as you're willing to stand and cheaper than upstairs
Beer is cheap enough and very good.
Good place to wait for the train
Can't go wrong with German beer! Try the Salvator, it's a dopple-boch meaning it's high ABV dark amber color, mellow Carmel taste, and a nice smooth malty body!
