Our first meal in Tokyo was in a little restaurant called Kazuki about a block away from the Tokyo Temple. It features Raman bowls. You choose your item from a menu on a vending machine at the entrance and then select the appropriate button on the vending machine and pay. Then you take your seat at the bar and they bring you your food. Instead of water they serve a weak drink called Mugicha. It tastes a bit like Postum or maybe Cheerio tasting water. I did fairly well with the chopsticks. The meat wrapped pot stickers in the 3rd picture are called Gyouzan .
