1. Owl N' Thistle
In a lot of ways, Seattle is built on the graveyard of the old city that burned down in 1889. The abandoned tunnels beneath downtown are creepy as heck, and the Owl N' Thistle is right at their mouth. The Irish bar gets all kinds of spirits, including a woman in a wedding dress and a very vigorous piano player.
