Anything I just have to do in NYC from 2/8-2/11?

I am a San Franciscan heading to NYC for three days next week and am curious for recommendations of anything I just must see or do or experience. I have been to the city a half dozen times before, but can never keep up with the latest and greatest stuff to check out. Anything weird? Wonderful? Tasty? Did you have a particularly memorable moment on a recent trip? Suggestions can range from free to pricey and outdoors or inside. Huge thanks in advance. I love you Flutherers!
