Where are some good places to sit and relax? I know there are benches, but I'm talking about somewhere comfortable. A coffee shop with couches or something would be perfect.

Panera or B.A.M. might work as long as you order coffee or something.

Depends on how long you want to chill out. I suggest the galleries at the Nebraska Furniture Mart as they have many galleries of furniture and even a theater display if u want entertainment for free. It's an unorthodox idea but a good one, otherwise I suggest Jazz the restaurant
