CC Attle's, a gay bar on cap hill, has a monthly fetish night that's been drawing a big, friendly, diverse crowd of kinky gay guys -- including a bunch of local furs! So come on out, in suit, gear, or street clothes, and enjoy the ambience and awesomely stiff drinks CCs is known for. And if you're in suit or at least 3 pieces of gear, those awesomely stiff drinks are discounted.
It's not everyone's cup of tea for suiting: it's packed, hot, and there's no place to change (although there is a coat / clothes check), but I've suited there several times and had a blast. There's no cover, and it's obviously 21+.
