I really like Tempe Marketplace. I always come here to see movies at Harkins. I also frequent the Stone Cold Creamery. It is a nice open air mall. If you know where to park it isn't too bad. There have been a few times where I have had to hunt for a spot but those were on busy days or holidays. I have been to a few of the restaurants and they are good too. There are a few I have been meaning to try like Lucille's BBQ.
I like to come here and hang out. They have some good outdoor seating and good people watching. It is also just nice to wander around.
