Yakiso Ryongpo Tenten is a yakiso ryongpo shop in Fukuoka that grills the buns on a teppan. It serves two kinds, basic and mentaiko, with a crisp bottom and hot juices inside. After ordering, the wait can run 10 to 20 minutes, and you break the wrapper with chopsticks to let the juices out before eating. During slow hours, the buns can come out stiff or cold.
