The Gangnam branch of this Baesangmyeon Brewery bar is a bit snazzier than others, but remains a good place to sample quality traditional Korean alcohol. Its signature Neurin Maeul makgeolli (milky rice wine) is the standout – it's divided into the four 'seasons', which refers to the differing production stages; you can sample each before ordering. Look for the rusty shipping container.
Jugs cost ₩8000 per litre (or ₩3000 takeway). There's another branch in Myeong-dong.
