Grill 640 is a meat restaurant in the back streets of Yeoksam in Gangnam, Seoul, where beef and pork are grilled on a hot plate. Diners choose thick pork collar, tenderloin, or Iberico emperor's cut, and staff grill the meat at the table, with taco plates and steamed egg served alongside. Side dishes differ by cut, and the dining room does not retain much smoke, so clothes pick up less of a meat smell. Seats are uncomfortable enough that knees touch the table legs.
