>>21464117 (OP)New Yorker here. We have a few different kinds.
The first are the neighborhood staples, some of which have been there for decade, selling good food priced for working people. Office districts like midtown and FiDi, and all over the outer boroughs, are where you find these. Nightlife centers have some good ones too. There's a taco truck down the street from me that I've enjoyed many times after nights of drinking.
Then you have the ones that locals go to occasionally because they're just that good, but word has gotten out so we go when tourists aren't clogging them up. Adel's Halal is a good example of this.
Then you have the ones that show up at food fairs, like Smorgasburg, selling $20 okonomiyaki and stuff like that. Now, some of these can be actually good, but some aren't, and they're all priced for tourists and others with more money than sense. Admittedly sometimes I just don't care and I'll splurge on something dumb from one of these.
They're an integral part of the food scene here and I appreciate the more interesting ones.
