Being unusual doesn't need to be a bad thing — the right amount of weird can make a place worth visiting. And Aria Antiques is certainly that. Tucked away in North Beach, this crazy antiques shop offers stuff like vintage mannequin parts, scientific diagrams, steampunk dolls, and tons of other items that wouldn't look out of place in a Tim Burton film. Just be sure to hit the ATM before you go — the shop is cash or check only.
