ELI5: How does grocery shopping work in New York City?

Here is what I mean:

1) Are there really large grocery stores in such a dense city?  Square footage costs in NYC would seem to make a large grocery store not possible.

2) If there are large grocery stores, where are they usually located?  Is there one whole floor of a large building, for example? (e.g. the Safeway take up all of the fifth floor of the building at 2323 4th St.

3) How do people living in NYC transport their groceries home?  My understanding is that most people living in NYC, or at least Manhattan, do not own cars.  How would one person purchase groceries for a family of five without a car?  I know they could just go to the grocery store more often and hand-carry what they purchase, but it seems like this would get very old (e.g. going to the grocery store every other day for eternity).

Thanks!

There are "large" grocery stores in the city, but not as large. None the size of malls. Maybe the size of a "large store". Or a basement, in the case of a Whole Foods.

You either buy groceries more frequently so that you carry less each time... Or get one of those infamous granny carts so you can haul your load onto the street or subway.

Or, typical of New Yorkers, don't go food shopping at all. New Yorkers love eating out since there are so many options here.
