This has been one of my favorite places since I was very young. Lately though, the service has been horrible on the past few occasions. This week, we were seated quickly and it was a very empty - only two other tables were filled. However, we still waited 15 minutes to be acknowledged. We would have moved on to another restaurant, but this was the third we'd stopped at where the wait wasn't over a half hour. We watched two waitresses wipe tables. I don't know why the camaraderie among employees doesn't exist here where one of the others could have gotten our drinks while our waitress was at the other tables.
The food is just as good as it always has been. The pizza is very good - they have some of the best dough and cheese around. They make grilled chicken salads the way Pittsburghers like them - with fries and all. The food is as good as it always has been, and that's the only thing keeping the rating.
I would say your best bet is to order take-out. Then you won't have to deal with it.
