I would love to find a place in NYC that sells the version of Chinese shaved ice that I enjoyed when I lived in Houston.
We called it "Bing" and we got it at May's Ice Cream in Houston's Chinatown. It starts with a big cup of shaved ice and then you can add various toppings such as grass jelly, almond jello, different varieties of sweet beans, tapioca, etc. After they add all your toppings, they add some condensed milk on top. Great hot-weather sweet treat!
I've seen versions here with brightly-colored sweet syrups (which I'm not crazy about) and sometimes the beans, but never with the wide variety of options to choose from.
