The Big Apple! The best thing about the "city that never sleeps" is the astounding variety of ethnic food you can find there. From ultra-expensive, nine-course meals to a gyro from a food truck, New York City seems to have it all.
If you're on a gastro-vacation in New York, look into taking one of of the many walking tours that teach you about New York culture through its food. Every neighborhood and ethnic enclave in New York City has its own special style of cuisine. Since New York is a city of immigrants, you'll find kosher, Peruvian, Italian, Jamaican, Chinese, Puerto Rican ... pretty much anything you can think of.
