A Mos Burger just opened up down the road from me. Hurrah! It's one of the few fast food places that has something decent on the menu that I can actually eat (the rice burger). Mos Burger bills themselves as the most popular burger place in Japan. Most of their menu also seems much healthier than anything sold at the other burger franchises around.
Several months ago someone took me to try a rice burger at the first Mos Burger restaurant to open in Australia and I found it very good. The rice paddies are made from rice pressed into shape. The rice burgers are not that big, so my plan thus far has been to buy two at a time. The plan is working well.
