New York and Fabric Shopping - Where should I go?

Start spreading the newwws,
I'm leaving todaaaaay .... well in three weeks actually ...

I'm heading to New York real soon and I need your help! For those of you that have visited before, where are the best 'seamstress' places to go?

Me in my Tessuti New York Cape

June 2nd is the day I fly out of Melbourne and after about a 20 our flight (Dear.God) I will be arriving in New York on ... June 2nd. No I'm not handy with a flux-capacitor, it's all thanks to the International date line.

My husband and I are jetting over as part of my prize for winning the wonderful 2011 Tessuti Awards of which my vocal chords have still not recovered (excessive screaming and hysterics will do that).

I am having daily fantasies about talking to squirrels in central park, eating slices of pizza the size of my face, wearing over-sized jerseys at Baseball games and pretending that the TV show 'How I met your mother' is real and that I'm bestys with Robin Scherbatsky.

The very first time I ever visited the U.S. was with my besty Lisa.

And this happened ...

Let's be honest, this photo just makes me want to go back STAT.
This guy was a singer of a heavy-metal band and had recently had his tongue surgically split to resemble a serpents tongue. His name? Lucifer? Darth Vader?

No.
Keith. I kid you not.

Some how this just makes him even more awesome.
Admittedly this was in Hollywood, where I swear to GOD every guy there was named Josh and was an actor. After being dropped off by a bus in a random spot in Hollywood and being convinced we would be murdered we ended up meeting some locals and having one of the best nights of our lives.

This also happened on that visit.

An "interpretive dancer" from New York, and his day job? A child physiologist. Seriously. I still cannot look at these photos without falling into hysterics.

Definitely the most exciting thing about this trip is the Mecca of fabric stores that I can devour. My credit cards have practically disintegrated in my wallet out of fear. I already have Mood on my list of 'must visit' and I've already packed a brown paper bag for when I start hyperventilating in the store.

And so now I need your help.
Locals or visitors of New York, where else is a 'must visit' for all things fabric, notions and fashion?
Or perhaps there's something unrelated to sewing that I simply must do! Let me know!
