I went to Teskes Germania this past weekend to celebrate Festivus and a friend's 35th birthday. If you're going to visit, no need to get dressed up. The restaurant/ bar is somewhat of a traditional german restaurant with a bar in the front and some long tables in the back. Unlike Germany though, the tables weren't the long tables with benches you might be used to in the tents of Octoberfest. The idea was the same though... communal dining.
I lived in Germany for about three months and was always a fan of the pork knuckles so I gave that a try at Teske's. While not the best pork flank I've ever had, it was a great meal, very hearty portion, and the potato side dish and crout was fantastic.
The beer selection is quite good. Plenty of Pilsners, Weisen, and Dunkel beers on tap or in the bottle. So pony up and order a liter in a classic tent stein.
The decor is nothing to write home about and probably hasn't been updated since the early 70s. If you're trying to impress a date, this place is probably not going to do the trick for you. If you're with a big group who's looking to put down a couple steins of German beer and want to prost with the band, then Teskes is a fun night out.
