The pizza here is really good, but like so many other places in Tempe, the service is fair at best. I don't think the staff likes hearing "I have a groupon" from their customers, either. Luckily they have a pickup counter if you just want a good pizza without being ignored by the not very busy looking bartenders.
3 stars seems too low because of the quality pizza, clean bar, and cold beers on tap. 4 seems too high because of the unattentive service and prices. Settling on 4 stars because they frequently have groupons.
