Sure, but more places take card, and fewer people carry as much cash. Or rather, people carry less cash.

The fact that a business "famously" is cash only seems to support this, as that implies that it's becoming more unusual.

It’s certainly unusual for a famous restaurant to not accept cards.

Everything else is a crapshoot. If you don’t have cash you aren’t getting dumplings in Chinatown. And that’s just a bummer!
