I was randomly in Madison for the first time ever and just wandered down State St looking for eateries, the outside of Cosi looked promising so I went in. It's adorable inside, great decoration and layout. I was there at a slow time, so it may not always be true, but the food was extremely fast. And very delicious. I had a toasty whole wheat pesto chicken melt, and it was all I could have hoped for.
