Max's is one of my favorite restaurants in Pittsburgh. It's the Kennywood Thunderbolt of Pittsburgh restaurants. The Thunderbolt is considered one of the best rollercoasters in the country. It's not the fastest, it's old, it doesn't have the biggest drops or flip you upside-down. And yet it's great. It's classic. This is Max's Allegheny Tavern. I'm sure there's better German food with cuter waitresses somewhere out there that doesn't have the decor aesthetics of your grandma's living room. But who cares. This place is just right.
Final note, I can't speak for the brunch buffet. I went in there for the buffet once and decided that my money would be better spent on the menu.
