There is a restaurant which is all you can eat rice near my house. The restaurant is called Yayoi-ken. Normaly, a restaurant of all you can eat is almost meat menu. However, the menu of this restaurant has some Washoku which is grilled fish or stire vegetables. A restaurant like this is helpful for poeple's health who eat out side. Eating a fast food such a KFC or McDonald's is good sometimes but eating too much will cause gain a weight absolutely. Those restaurants are popular in Japan aswell but middle age and elder prefer more healthy restaurants. I can't eat rice a lot but restaurant of all you can eat rice is very popular in philippines such a Mang INASAL. So if Yayoi-ken opens to expand their business overseas, it might become popular.
