I've been to NYC a few times and never seen or heard of anything like that, but it sure does, just like everywhere else in the world, even if it's clandestine
About 10 years ago I was heavy into online poker and live tourney's. I would play a few times a month and I heard about a few games a week. I would often be notified by a group text message of games in Manhattan and queens. I'm sure these games are around still, but you're not going to see them on a subway poster.
