These are our favorite way of dining in Japan. You simply choose the item you want from the picture, press the button and put in your cash. Out comes a receipt and your change. You sit down,hand the receipt to the cook and presto your meal arrives in not time. There are lots of these places around doing curries, noodles and other quick meals. Very tasty and super cheap. You can get a beer, salad, and curry with rice for around $10- very hard to beat.
