Favorite city in USA to Visit

Mine would have to be currently Los Angeles which I've been to a couple times with my mother. I love the weather, the shopping is great, and I didn't find the city intimidating at all which I was scared that I would. And there is so much to do!

So what's your favorite city and why?
 
Either New York City (the museum, the theatre, shopping, the restaurants . . . )

Or

Newport, Rhode Island. I went to college there. It's a gorgeous town. I love going during Homecoming Weekend. (Our team usually loses, but just going and watching the game is always fun.)
 
i LOVE new york city...
that place is just so magical... especially since it appears so much in movies, tv, books, etc..
san francisco is a close second... i love the water and the weather
