There are a few around. 21st Street Coffee in Pittsburgh is one example (http://21streetcoffee.com/ http://21streetcoffee.com/). Their main area on the 1st floor is for regular customers, but they have a large upstairs loft outfitted with your typical coworking desks, chairs, couches, etc and access to wifi. I think it's something like $10/day for the coworking space and that also gives you a 20%(?) discount on coffee, etc.
