This ain't your grandma's tour. Unless your grandma was secretly scandalous. Join our group of LGBTQs on Thursday, May 14 at 7pm as we take a private, one-hour Adult Underworld Tour of Seattle's buried first story and the seamy tales it hides.

You probably know that Pioneer Square was raised by one story in the 1890s to prevent the sewers from flowing backwards. But did you know that the left-over basement level became home to a host of gambling halls, opium dens, and speakeasies?

Find out more as we slink through the shadows. Then digest the dirty secrets with your fellow subterranean travelers over a cocktail at the Underground Café.

This tour is not for tourists. Or anyone under age 21.
