Holmes and Lupin Board Game Cafe Seoul National University Station Branch is a room-style board game cafe in Gwanak-gu, Seoul, where groups play games in private rooms with drinks and snacks. It sells sotteok sotteok and smoothies, and groups of four to five or more get a dedicated space and can enter right away. All game manuals are laminated. The shop is on the third floor, so visitors with knee problems should be careful on the stairs.
