Drive-thru windows at fast food restaurants have become commonplace in Japan over the last decade or so. But they're still a rarity in congested areas like central Tokyo where not only do most stores not have drive-thrus, they don't even have parking lots. A trip inside some of them can reveal surprisingly little room even for customers to sit down and eat.
With the interior being crowded with dining patrons during the busy lunch hour, it only makes sense to provide a "walk-thru" window for customers purchasing take-away lunches.
