As far as Pittsburgh restaurants go I'd recommend Whitfield for brunch.
I had the Whitfield breakfast and my boyfriend had the roast beef sandwich.
I really liked my breakfast. It comes with a hash brown that is made of beets which has a really nice flavour. The only thing I'd change would be to have a bit more food.
My boyfriend said the crust on the bread of the sandwich was quite hard so it made it difficult to eat. Also said taste was just ok.
Our server was great. He was friendly, knowledgeable, and attentive.
We have also been to the bar in the evening. It has a good atmosphere, one of the better in the Shadyside area. There are a number of chairs and couches throughout. The only had one (or maybe two) servers for the entire area. That, coupled with the fact that there were only two or three bartenders made service quite slow. I'd return for sure, but I'd try to order from the bar instead of a server.
