Jjukkumi Blues Sinchon Branch is a Korean restaurant in Seoul that specializes in jjukkumi, stir-fried together with samgyeopsal at the table. Gim, flying fish roe, and perilla leaf are unlimited refills, and mussel soup and steamed egg come as basic side dishes. The interior has a retro style that recalls a 1960s classroom. On weekends and during peak hours, the wait can run up to an hour.
