Think of the Prancing Pony in the Lord of the Rings...a place where locals and travellers can mix and mingle and converse as much or as little as they please.
I love the idea of a hot yoga session before heading to the pub for a couple of pints and some darts.
Central Europe is losing the vibrant cafe culture it used to have, where people could sit together for hours and chat. Cafes today often blast loud pop music and send staff around more frequently to pester clients who seem to have finished their drinks, as owners believe this will prevent people from loitering. Instead, customers will quickly drink what they ordered and then get out, freeing the table for other customers.
Perhaps in the USA the situation is different, but I live in a city with a tradition of quiet, intellectual cafes that goes back centuries, and was still like that a decade ago, but now I am hard pressed to find a single place that would be pleasant to socialize even with my friends in, let alone mingle with other regulars and strike up conversations with strangers.
I'm much more likely to be pushed out the door at my local brewery or bar than I am at a coffee shop. If I had to guess it's because coffee tends to be a grab-and-go whereas beer cannot be served in a to-go cup so it has to be served and consumed inside the building with few alternatives if the seats are all full.
Unfortunately, it comes with some dangers...nicotine.
The days of hookah bars in many locations are probably numbered, since public health is focusing on gradually reducing tobacco use to zero. For the time being hookah tobacco might still be sold for someone to use in the privacy of their own home, but forbidding smoking hookahs in public spaces is a simple and effective step that the authorities can take.
Many meditation and Buddhist activities are free or donation only. It's a common attribute that Buddhist retreats are completely free before and during the event, and only after you receive a piece of mail soliciting a donation.
There _are_ more commercial meditation based activities but those are more lifestyle than spiritual.
Also, due to movements like the Hare Krishnas advertising free events (often without specifying that it was the Hare Krishnas or whatever other sect organizing it) for the sake of bait-and-switch recruitment, people are understandably suspicious of any vague "spirituality" or "meditation" event where free entrance is advertised.
To acquire friends one has to get to know people, and also people have to know one. It takes time to open up.
I'm not saying bars were this magical place. No. Bars were the place people who for some reason spent enough time together to get to a bar went to.
I don’t drink anymore but when I lived in NYC I went to the neighborhood bar and was part of a loose knit group of people who went there too. Classes, schedules and fees don’t point to the same thing.
I do miss the mid 90s indie coffeeshop scene.
I think some of these things may die off when people our age have kids. I didn’t have a kid when I did these things before. Maybe schedules and fees facilitate third place activities when you’re negotiating time with your co-parent. Now my kid is mid-teens and I have my free nights for third place things. But I’m not likely to attend a thing at a time and pay a fee. I’ll go for a trail run, with my partner or by myself.
Your white upper-middle class is showing
Yoga classes, coffee shops, CrossFit, meetups, hiking groups, rock climbing, dance parties, marathons, evening painting classes where they serve wine, improv comedy shows, improv comedy classes, cooking classes, language classes, indie band shows of every type. Meditation, Buddhism, any kind of spirituality you might be into. Literally everything just a few clicks away on Google. You don't need to "know somebody", you can just go. Go a few times in a row and make conversation with people, and suddenly you've got community and new friends.
Modern culture is an incredible smorgasboard where you can connect with every type of person through pretty much every type of activity known to man, whether athletic or artistic or spiritual or educational or all four.
The bar was a kind of lowest-common-denominator location that often came with a drinking problem. Bars still exist, but today's alternatives are almost infinitely more varied and vibrant.
