Takarajima is a monjayaki restaurant on Tsukishima Monja Street in Tokyo. It serves mentaiko, mochi, and cheese monjayaki and seafood dishes, along with okonomiyaki, yakisoba, and desserts, all made with rice-flour batter. Orders are placed by scanning a QR code on a smartphone, and staff cook the monjayaki, okonomiyaki, and yakisoba. On holiday evenings reserved seats fill up and entry is tight, so reservations are needed.
