Goko is a restaurant in Seoul that serves onigiri and Japanese-style rice balls. The tuna mayonnaise onigiri combines creamy mayonnaise with a natural sweetness, while the Yeosu jiri myeolchi is dry-roasted until crisp. When two or more are ordered, staff ask which one to eat first and make them one at a time to match the pace of the meal. The clean, orderly restaurant has separate men’s and women’s restrooms, accepts simple payment methods, and offers parking.
