Iroha Nishinaka is a monjayaki restaurant on the monjayaki street in Tsukishima, Tokyo. It serves mentaiko and curry monjayaki along with okonomiyaki. Customers grill the food themselves by default, or staff will grill it if asked. The finished monjayaki does not look appealing, and smoking is allowed indoors with no ventilation fan, so the room can fill with smoke.
