My local Whole Foods (good for prepared food) was opened until 10 before the pandemic. During the pandemic they changed hours to close at 9. A few months back they changed to open until 10, that lasted about 2 months. Back to close at 9 - perhaps partly because of labor shortage.

Walgreens on Downtown Crossing - which has some prepared food - started out as opened 24 hours, then opened to midnight. Last I was there they were kicking people out at 10. Just not enough reason to stay open, although it might also be because a higher percentage of people in the store weren't there for shopping after 10.

There is always South Street Dinner.
