Beef stew lunch = 700 yen ($6.73 €4.93)

I ate a beef stew lunch at a local restaurant for 700 yen ($6.73 €4.93). The owner of the restaurant reformed his house into his own restaurant. If he rent a space for the restaurant, he has to pay much money to the landlord. So to save his money, he decided to use his own house. The restaurant does not face the main street, and we have to go through a narrow path to reach the restaurant. A stranger can not find the restaurant.
