iPad Menu for Sumo Sushi Restaurant. The idea of making a digital menu was to substitute waiters with digital version of a menu to make the restaurant more productive and save its budget. Using such menus help clients to order whatever they want by clicking buttons. This menu prototype (UI/ UX) was based on a particular group of people who like simple and clean menus, who have allergies on some ingredients and like to use free Wi-Fi. In order to get Wi-Fi password, a client has to play SUDOKA game and figure out digital number, which is supposed to be a right password.
