Each table in the restaurant res-taurant is to be fitted with a frame bearing the menu and a series of electrical elec-trical "press buttons" corresponding with each item in the menu. The customer cus-tomer sits down before the already laid table, with a neat pile of glistening glisten-ing silver on one side, chooses tho dishes which he prefers, and presses the corresponding buttons In turn. In the kitchen of the restaurant the number of the table and the number of the course required are signaled on. a screen to tho chefs and ttyeir. ing Hoc dish appears in a little lift nt the side of the diner's table. The customer helps himself, presses a button, and the dish disappears as silently as it came, leaving at the side of tho plate a little aluminum ticket indicating the sum to be paid.
