Now when I say you pay for it, I mean it. The cheapest beers at Biergarten will cost you around $7 or $8. And don't think you can get off easy ordering a Miller Lite, because there isn't much of a discount. Considering the ABV of many of the German beers, you are better off going with a Spaten Optimator or Paulner Hefewiezen in order to optimize your buck. Also, don't count on happy hour discounts as none exist.
The large tables at Biergarten are shared, similar to what you see at any German beer hall. Some fat hog sat down next to me and ordered the sauerbraten and proceeded to send it back two times because the meat was too fatty. I'm guessing that she was not familiar with brisket. This sauerbraten dish consisted of vinegared beef brisket, mashed potatoes and sauerkraut. I thought it was fantastic. Although fatty (as brisket should be) the meat was extremely tender. The portion was awfully small for the $14 price point, but I've already explained that you will be paying dearly for the wonderful view.
This is my friend Eric. Eric ordered the Currywurst and smoked mussels. I believe he had a pretty nice evening until he got stuck in one of the Hotel Monaco elevators on his way out of Biergarten and was stranded for almost an hour. (The elevator situation is not ideal.) I have scarcely seen him since and I'm pretty sure he blames me for his misfortune.
Overall, Biergarten is a must visit. Arrive early and enjoy a glass of wine at no charge in the Hotel Monaco lobby from 5-6. This will help defray your beer expenses later in the evening.
