Your addition of "abundantly" makes things more ambiguous, but I think the choices available in most large US cities is _decent_ after midnight. Can you get absolutely anything like NYC? No, probably, not. But burgers, diners, and fast food are all generally available. That's also ignoring 24/7 grocery stores like Walmart that can fill in the gaps if you're craving something hyper specific. Perhaps you can't buy it ready-made, but you can buy the ingredients!
