Webster Hall is a solid venue, and a frequent stop for many great bands on their rise to glory. If you've only got a few nights in the city, chances are a great act will be playing here.
My favorite Chinese food spot. The best Peking duck! Ignore the C health code rating in the window, they must have made a mistake ;) Also, It's BYOB with no uncorking fee, go crazy.
This is the new bike share program of NYC. It's amazing. I went for the 1 year membership for $95. You can also get day passed for around $10. There are stations all over the city. You can now have a wonderful day changing between walking, biking and the subway. Finally, I can stay away from the crazy cab drivers...
