Seeing famous people here is like seeing anyone else. They are all over the place and only the tourist hound them.
As far as shopping-when I speak of shopping I am not talking about street vendors or tourist shops- I am talking about 5th Avenue, Madison Ave., 57th St, Henri Bendels, Bergdorfs, Soho, The East Village, 8th street for shoes (where the BEST SHOE STORE IN THE WORLD IS WWW.PETITPETON.COM ) amonst many other ares- there are amazing shops here for vintage, designers goods, consignment, specialty shops- whatever you can imagine.
ANd of ocurse if we are talkign about discounted desinger goods- Century 21, Loehmans, Filene's Basement, and The Designer Shoe Warehouse- just to name a few.
