Bas Burger Yeoksam serves handmade burgers and beer in a basement space directly in front of Yeoksam Station Exit 3. The menu pairs a double bacon cheeseburger and a chicken burger with Bas Lager, and potato chips and sauces are available for self-service after ordering. Single seats make it convenient for eating alone, and although the lunch hour fills with office workers, turnover is fast so waits are short. The chili mozzarella cheese bar is on the spicy side.
