Four Chairs Sadang is a small bar in the alley by Sadang Station Exit 10 that serves cocktails and malt. The staff ask about your preferences and then recommend or make cocktails that are not on the menu, alongside signature cocktails and various spirits. It usually stays open until 4 a.m., and the bar table has only six or seven seats. On weekends seats are hard to get, and visits by groups of four or more are difficult.
