This vegan dosa cart in Washington Square Park is just as legendary as any other New York City monument, and so is the dosa man who runs it (named Thiru Kumar). Ny Dosas serves South Indian staples like vegetable-and-curried-potato-filled dosas, roti, and samosas every day (except for Sunday) from 11am to 3pm out of a little cart by the dog run in the park. All of the dosas are served with coconut chutney and sambar, and you can pay with cash or Venmo.
