Let's see. Go to 14th street and union square. Union Square is always a lively crowd. There's a whole foods play, and the huge best buy where artist go for their album signings. There's also cupcakes by melissa for your desert needs. There they have Webster's hall which has a lot of interesting parties mixed with celebrities and things too.
Further down from there is Soho which is south of houston street, a nice party area and shopping area. That's where Uniqolo is, a great place, like a better version of H&M; also the Bape store has a lot of celebrities that come there, and there's a lot of great places to eat and trendy bars. It's my favorite area of NYC.
Also you have the meatpacking district which is probably my favorite party area in New York City.
In Harlem you have soul food resturants Slyvia's and Ruth Chris if you like that type of food. You also have the Apollo theater where Michael Jackson and a lot of the greats started at, a great tourist attraction.
You have Central Park which is like beyond huge.
In Brooklyn you have the Brooklyn Museum and the Brooklyn Circus which is like an urban style clothing store with a lot of cool guys there. There's also the Brooklyn Bowl which hosts a lot of free parties, with a lot of them being dj'd by Solange.
Cosi is a great place to eat. They are all over Manhattan. The Bronx has Yankee stadium.
