BAR VIER sits in an alley between Sinyongsan Station and Samgakji Station in Yongsan-gu, Seoul, on basement level 1. It is a speakeasy-style bar serving cocktails and whiskey, with seasonal menus and storytelling built around its signature cocktails. The bartender explains each cocktail and helps with orders, and food is available to eat alongside the drinks. It is an expensive bar, not a cheap one.
