If you eat lunch near campus or on Mill you have to give this place a try. It might be difficult because it's somewhat hard to find. When you're on Mill, between La Bocca and Bank of America, where the escalator is, walk straight back. Keep walking past the ASU buildings and you'll see Center Bistro. The first time I went there I didn't walk far enough back and was totally confused for a couple minutes.
Anyways, once you find it you're set. The food here is amazing. It's all organic and delicious. I've been here twice, once I got the thanksgiving sandwich and the first time I got the daily special, curry rice and shrimp. Both times I was beyond impressed. I've also tried the bruschetta, the brie and fig was amazing.
I'm also really impressed with the service. By the only second time I'd visited they remembered me, maybe not my name but definitely that I'd been there. They always seem helpful and upbeat.
Great lunch place on MIll with a little less guilt than Five Guys ;)
