Square cafe is a perfect brunch spot. As a Pittsburgh native, I'm familiar with the other local chains and this one is by far my favorite. A lot of variety and solid service. Pittsburgh restaurants tend to start out great and then slowly deteriorate over time, but Square Cafe has avoided this curse.
I give it 4 stars because although the food is really good, it's nothing exceptional. Also they do not offer any alcoholic beverages ( I don't think).
