|Drive thru Curry House CoCo Ichibanya, in Fukuoka Japan.|
These restaurants are hot noodle places like Nagasaki Chanpon, Japanese curry houses like CoCo Ichiban, and even Yoshinoya (beef bowl restaurant) has a drive thru order window.
I'm not sure if I want a hot bowl of noodles of my lap driving home, but I am sure the convenience of having fast food other than McDonald's is a sure seller.
I think most of the people who order their food park and eat in their cars or live close enough that they can eat at home.
Next time I will have to give it a try. With 4 kids at a restaurant sometimes it is a lot more civil for us to eat in our car rather than to have a table.
