I will be visiting NYC from Boston over the next couple of days, staying at my brother's place near 86th Street on the Upper West Side. I will be at a loose end for at least one afternoon, and would like to spend it eating delicious things I can't normally get.
So, what I'm looking for is a part (or parts) of town that I can get to by subway where I can find lots of light street food to eat. I mean, I could just go to one restaurant and have a great lunch, but I think I'd have more fun wandering and nibbling. (My appetite's smaller than it used to be, I've been trying to lose a little body fat, and I'll be having dinner with my brother in the evening, so multiple lunches are out of the question.) Where is the best place to go and do that?
Again, I'm especially looking for food I can't get in the Boston area. Boston has a decent variety of Chinese, Vietnamese, Indian and most Latin American foods (not just the usual, but things like Dominican and Venezuelan). Calvin Trillin makes it sound like the Jackson Heights subway stop on the 7 train is a great place for nibbling street food, but it also sounds like most of it is Indian or Latin American, and those aren't what I'm mainly looking for. Is there somewhere I can go in the city that I can wander the streets and get a Nigerian peanut kebob followed by a little bowl of Burmese noodles and a Georgian khachapuri? That's just an example, but I hope you get my drift.
