"The Cart" on 53nd and 6th Avenue is one of the best NY dining experiences I've ever had*. They serve a choice of meat (chicken, gyro, or both) over rice and salad. You chose from three sauces (hot, white, BBQ) and you get some warm pita.
1. The line was 30 minutes long at 8:30 PM
2. Order "combo meat with white and hot sauce"
3. Forget the BBQ sauce
4. Don't be alarmed at the amount of white sauce they put on. It looks like a lot, but once you mix it in, it's perfect.
5. If you pay for water and then tip the main guy as you pay, one of his helpers will run over to the water stand (a few yards away) and pick up your bottle at the (separate) drink cart.
(*BTW, like many chowhounders I've have had DiFara's pizza, I have eaten at Aureole, Shake Shack, Burger Joint, Nobu, Patsy's Harlem, Dounut Plant, R.U.B., etc. This is in the same league of greatness.)
