These are some recommendations from my friend Andrea (as recommended to her from a friend at work):
Ground Kontrol – An Arcade/Bar in Old Chinatown. We should go here!
There is also a haunted pizza place (I think it was also in Chinatown) (note: i found it, it’s called Old Town Pizza ) and underground tours of Portland where they used to kidnap people to make them into sailors. We didn’t go to these, but they sound cool.
(note from me: the Shanghai tunnels were less scandalous than I had hoped for but still underground passages are really intriguing spaces and it could be a good tour.)
