Well I will start off by saying I'm from NY.. We have a real Chinatown and a mini one (Flushing) and our "mini" one still trumps this Chinatown. But I might be bias here...
I will say this Chinatown has a few photo ops at the sun yet Sen Area and the gates otherwise you will find stores that sell random stuff that you don't need and Chinese bakeries, a chained bubble tea place, chain hot pot place and a few dimsum restaurants. I wouldn't make it a day event or even an hour event for this place maybe just route your destinations through it so you can see it... But really imo there is nothing special to be found here except the sun yet Sen place.
Sorry!
