Bikkuridonki Dotonbori is in the Dotonbori area of Osaka and serves hamburg steak and breakfast items. The hamburg steak, the main menu item, comes in small, medium, and large sizes, and even the small is large. Orders are placed on a Korean-language tablet, and payment is self-service: scan the QR code on the receipt at the kiosk at the entrance. The hamburg steak portions are large enough that even an adult man struggles to finish a large.
