Grill Demi is a Japanese-style Western restaurant in a Kyoto alley that serves hamburg steak and Neapolitan spaghetti. Its signature gyutan stew hamburg comes on a sizzling plate with a rich demiglace sauce that keeps bubbling until the end of the meal. The Neapolitan spaghetti set arrives on a hot iron plate, while the hamburg set includes rice and soup. With only a few tables, the lunch wait can run up to an hour.
