Plusplusminus is a wine bar in the Jeonpo alleys of Busan that serves natural wine with pasta and anju. The rigatoni pie holds three kinds of cheese and stays thick as it sits, while the guacamole pork steak pairs sous-vide samgyeopsal with tangy guacamole and a sweet-and-spicy sauce. Staff give detailed explanations and recommendations for the wine, which makes choosing a natural wine easier. The dark room is set up so guests can pick both wine and highballs.
