“Towns”, yes, but NYC? It’s so dense that it can easily support the vast majority of amenities - as can most big European cities.

When’s the last time you went to Bubba Gump or Hard Rock Cafe? That’s the kind of crap most tourism usually supports. There is almost zero overlap between the restaurants locals go to and the ones the tourists do because locals usually can’t be assed to wait for a table. To them it’s not a special occasion like a vacation, just another day.

I’ve found this to be an almost universal rule east of the Mississippi (on the other hand Californians have a weird fetish for waiting in line an hour to sit at a brunch place with less than a dozen tables).
