While some might say Tempe Marketplace is just another power center, I can't help but find myself hanging out there almost once a week. Usually for dinner or happy hour. If you haven't been there, here's a few highlights:
Maria Maria: Carlos Santana's restaurant has a lot going for it, but one of the top qualities is the atmosphere. The patio is big, the music is live on the weekends and the crowds tell you it's a pretty popular place right now. The food is also good, but not really the reason you go.
Cheeburger Cheeburger: Any place that has 80 different kinds of shakes or malts has my vote. I recommend the chocolate malt or the birthday cake shake. The burgers are also pretty tasty, with nearly limitless toppings.
Kabuki: If you're not a sushi purist, but enjoy rolls and cheap happy hour appetizers, this place is for you. A good place to introduce someone to sushi.
Other assorted chains: Chipotle, California Pizza Kitchen, Paradise Bakery, Cold Stone Creamery, etc.
