Talk to most alcohol-loving exchange students about Rainbow Bar and you might see a dreamy glossed-over look in their eyes–the legendary basement hookah bar has almost become a rite of passage for their years in Korea. With a small pond in the center, self-order bucket drinks, writing on the walls and floor seating, the bar plays into the hippie feeling well and attracts a lot of attention from fun-loving locals young at heart as well. You might get the feeling that the bar has somewhat passed its heyday, because it has–but there’s also no denying that there’s no other bar like it in Gangnam. It’s also one of the few bars in Korea very strict about verifying your age so make sure to carry identification with you!
