You know what I like about Japan? The mobile food. And I'm not talking about going to the drive-through at McDonald's for takeout. Albeit a dying tradition, in Japan you can still get some food such as noodles, octopus balls and "yaki imo" from street vendors who cruise the neighborhoods. If you have lived in Japan for any amount of time, you have surely become accustomed to the ramen man's whistle, the "tako yaki" man's song and the yaki imo man's cry. In my neighborhood, we even have a man who sells fresh fish from his bicycle. He'll clean and slice the fish right there for you on a piece of plywood attached to the rack on the back of his bike.
The reason I like food from the vendors is not because it tastes any better than what you could get at a restaurant. To the contrary, you can't be as choosy. You have to take whatever the vendor brings. But I like the direction the food moves in: toward you.
In the United States, where food is always stationary, you have to go hunting and gathering for food in restaurants and supermarkets. Try to get someone to deliver your food to you in America and it's called a gourmet lunch delivery service. That'll be an extra $5 charge for delivery, plus a tip please.
