I absolutely love this place - you can't get better than this in the 'Burgh! I've always sat outside when going here and I think it's great to be out in the open drinking some good ol' German beer.
Having been to the original Hof in Munich I can tell you it's very authentic. The food from what I've tasted is good and the beer is delicious - I prefer Hefeweizen's so I can't comment on the other type of beers.
Seeing that this is one of three Hofbrauhaus' in the U.S. (Cincinnatti, Las Vegas, Pittsburgh), Pittsburghers should feel proud to have the opportunity to experience this wonderful place. So grab some friends and grab a beer at the Hof - and try the pretzels with some beer cheese - delish!
