I'm a big fan of the Oregano's and most frequently visit the University Drive location (review: http://www.yelp.com/biz/oreganos-pizza-bistro-tempe#hrid:8voZ-Ol5ovGYBkkQDjREkQ)
This location has more spacious parking and a larger, covered waiting area, both of which are nice. We visited at off-peak hours, so I can't say whether this location gets busy during dinner like the University Dr restaurant.
The food was excellent here. We tried a thin crust pizza with applewood bacon and pepperocinis. This was one of the single best pizza's I have had. For dessert we ordered the half macadamia nut, half chocolate chip pizza cookie.
There were a few idiosyncrasies on this visit, however. Our pizza took a long time to arrive and came with added pepperoni by mistake, but we were happy to have it. We ordered a pizza cookie and the first one came too burnt to eat. Our server brought it just in case, but had already placed an order for another one. This lead us to have to wait a long time, but we were happy to get a properly cooked dessert and the item was taken off of our bill. The wait staff were friendly and efficient throughout, although I wonder if there are some problems or in-training staff in the kitchen based on our experience.
