This is my first time going to How Weird Street Faire in SF. I can tell you it doesn’t disappoint. We went there when it just started around 12:30pm, which is great with no lines. By the time we left around 3:30pm, there is a ling wrapped around the block.
It’s free but you can make a donation if you like. I love people’s outfits. It’s a mix of steam punk, hippies, burning man, and some nudity you know it’s SF. My experience wasn’t really weird, but it was a lot fun seeing people dressed in costumes. I’m definitely coming back next year.
