Iâ€™m planning a celebratory dinner in Pittsburgh in May. Iâ€™ve been to several restaurants there, but mostly casual. Would like to find someplace that feels more special, without being stodgy/too formal. The dinner is for recent college grads â€“ all sophisticated/adventurous eaters, so it can be creative or classic cuisine or anything in between. In short, not a burger or pizza joint, but not where youâ€™d celebrate your granny's 80th birthday either. Any recommendations?
