Ping pong and darts were mentioned in the previous thread, both of which are excellent for promoting friendship. Great, simple, fun ways to gather.
More active sports are good as well. Decades ago I played volleyball a couple of times a week, often socializing after the games.
Any activity or interest that you enjoy can work as well: music, reading groups, knitting....
All of these activities can provide pleasure and friendship. Not all of them will provide friendships with like minded Epicureans, but they're a start....
