J'adore la ville de Paris!
Champs-Elysees is one of the most beautiful mile-long stretch of road that I've ever seen. It's got the coolest shops and thing to see, and if you're walking up to the Arc de Triomphe, it will be one of the most unforgettable experiences that you will have in Paris. If you're hungry, though, and don't want to spend a lot on food, avoid this street like the plague, and go into one of the little side streets instead and eat like a local.
