A Chinatown visit is always good....New York Noodletown - bustling, loud, lots to look at and hey - who doesn't like noodles! ....or maybe one of the soup dumpling joints....i'm spacing on the name of the good one.
Sure I have some ideas Balki. Take her the water taxi to Water Taxi Beach and have a burger or hot dog. Or, maybe you should take her for a walk across the Brooklyn Bridge (although its hot) to Grimalis and Brooklyn ice cream. My two year old loves to go for dim sum - gets a kick out of the carts.
