Bento are box lunches. Fast, easy and cheap. What more could you ask for after wandering the streets of Tokyo? The ingredients in bento vary greatly (some have sushi, some have pickles, etc.), and most bento stands will offer a wide variety, so it usually isn’t difficult to find a combination you’ll enjoy.
While bento boxes in all their lacquered glory are available at many restaurants, to-go meals are easy-to-find. This allows visitors to Tokyo to enjoy lunch in the park. Bento generally follow a standard of four parts rice, three parts main dish (meat or fish), two parts vegetable, and one part pickles or dessert. One caution about bento on hot days: make sure the ingredients are well-cooked or covered. Raw items should be consumed with caution unless the meal is prepared immediately before consumption.
