Big big fan of Tempe Marketplace - especially when it's not 110 degrees outside. I go here to see movies and with the assortment of clothing stores, Target, BN, and a great variety of food choices, I'm very satisfied. There's even live music on the big stage sometimes. It does get crowded, but what popular place doesn't?
And, if you're looking for a place to drink that isn't Mill or Old Town Scottsdale, TMP can definitely hold its own with a couple great places to grab a cold one with sometimes ridiculously good specials. I just wish they had a few more laid back bars, and not just restaurants with big bars in them.
