Makerspace / hackerspace. Mine does an open house every week and maybe 3-10 classes or other events most weeks.
To be honest, the regulars there kind of feel like drifters. Not really working on anything, not really socializing. A lot of them talk a big game about crypto and entrepreneurship, but don't ever seem to make progress on their goals. It's not the healthiest place socially to spend a lot of time.
