Van Leeuwen Ice Cream has the best ice cream in NYC - they use super high quality ingredients, and you can definitely taste the difference! They also have heaps of vegan options, which are just as delicious as the traditional versions. My favourite flavour is Brooklyn Brown Sugar. Expect a bit of a queue in summer, but the wait is worth it! You could take your ice cream to Elizabeth Street Garden just around the corner, for a nice spot to sit while you eat it.
