If you've ever been to New York City and wandered around the area of 6th Avenue and West 53d Street -- and as a tourist, there's a pretty good chance you have since it's in the area of Rockefeller Center and the corner that the New York Hilton is on -- you've undoubtedly seen an omnipresent food stand there where meats and onions are cooked on a griddle day and night and mounded in a corner of the hot surface awaiting customers.
You may have even ordered a pita sandwich there. I did, many, many years ago, on one of my early visits to the city, while attending a convention, at the Hilton, in fact, in the days before I became a food writer. It was convenient, and cheap, especially for New York, and for someone unfamiliar with the city an easy and unintimidating choice.
I'm sure at the time I thought I was experiencing real New York food.
