Take-out restaurants (Take out Bento restaurant)
Bento (lunch box) restaurant is unique to Japan and may be something new for foreign visitors.
These restaurants offers set menu for take out only (no consumption in the restaurant).
Of course you can bring the bento to school. Most of these shops meet to customers’ specific requests offering only vegetable or meat if you like it.
It is most recommendable for customers with allergy problem or are particular about the type of food to take.
Price of a bento ranges from JPY300 to JPY700 and is much cheaper than to eat at a restaurant.
