Fish and meat go straight over the coals, and come out when they are ready rather than when the ticket says so. The grill sits in the open, which means the timing is done in front of you instead of behind a wall.
It is the part of the kitchen guests notice first — the skewers, the smoke, and someone standing over it the whole service.
