Ajidokoro Umeshima
A ranch-operated Iki beef specialty restaurant. Serves the legendary Iki beef, only about 40 head shipped per month, directly without distribution channels. Incredibly good value: 1,500-yen lunch plate featuring Iki beef. Tabelog 3.47 (225 reviews). So popular at lunch that it is always full, drawing visitors from outside the island.
Tabelog 3.47 (225 reviews), Google Maps 4.3 (52 reviews). Both locals and tourists are amazed: you can eat Iki beef at this price, and it is fresh because it is ranch-direct. Lunch is perpetually fully booked. Many regular customers say they keep coming back.
