Very nice place with Latin Jazz tunes in the back ground and a great atmosphere. I bit pricey, but the cuisine is incredibley good and worth it :-) Make sure you order a "macho mojito" when you get there.
Another hot cuban joint to hit is on w46th street between 7th and 8th, you can't miss it.
STAY AWAY from Ipanema (13w46st), Looks like a nice place to eat, but I know better ;)
