As the other reviewers have pointed out, W 47th Street is the center for diamond shopping in New York City. With over 2500 shops, there is no excuse for paying too much for a diamond here - haggle your way to the cheapest piece of jewelry you've ever bought for your loved one or for yourself! Then skip the hustle and bustle and head to the TKTS booth - there are discount tickets on Broadway shows sold here every day. That's a much better way of relaxing and having a New York kind of night than hanging around Rockefeller Center would be. All in all, 47th Street alone will provide you with enough entertainment for an entire day.
