Ramen [moved from Boston]
There was some coverage on ramen in NYC in the NYT: http://www.nytimes.com/2004/11/10/din...
I've tried Momofuku's and Rai Rai Ken's. Definitely enjoyed the latter, but I thought other stuff was better at Momo's. (e.g. the crispay fried pig's tails, pickled veggie mix, steamed buns, etc.)
