If it is not Octoberfest, there is no reason to go. This place is completely overrated. The food is not good. I had pot roast and it was so sickly sweet. The schnitzel was overcooked to the point of mushy. It's not like the restaurant is supposed to be high end, but I expect more for $15 entrees esp. in Pittsburgh.
Sure you can go for the beer, but Penn Brewery beer is widely available in many bars. It's not like the Octoberfest food is that good either.. You go more for the party.
