Rule of thumb: Koreans do their spas less hard core than the Russians/Scandinavians but they also tend to be gender-separated. I prefer the Russian spas because they tend to be more hard-core. LA's is built in a former crematorium; one of the body-burners is now in the hot banya, with railroad tracks still leading out of it.
Banya 5 is dope. It's the only one. The one in Everett is skanky but I hear it's being remodeled/sold/whatever. I still have trigger finger in one of my fingers from a visit to Q in 2018, fuck that place.
