I feel like this video (link below) does a good job of explaining why a lot of current third places aren't quite meeting the need, or just don't really fit the definition of third places.

I can think of a few places that meet most of the criteria near me, but there's very few. The closest ones are probably the gaming shops, where you can show up and just hang out playing games with friends for free - but those are kind of geared towards specific activities, so you can't always show up and just hang out with others whenever, as there are usually only regulars on certain days of the week, and often they are involved only in playing a game, not casual conversation.
