I love Quaker Steak and Lube. They have to be one of the best chicken wing joints out there. I've been to the one in Dayton, Ohio a number of times, but it's been a few years.
While in the Pittsburgh airport I saw they have a small setup here. It is the typical food setup for an airport so nothing really special. They do have counter service which can be fun. I had a short time, so ordered a small order of hot wings and a root beer. They serve their root beer bottled, so no refills. The wings took quite a while to arrive and the server was hard to find most of the time. The wings, however, were as good as the ones I remember in their full restaurant.
