Lunch ON! S2013E01 - One-coin Lunch

A survey shows that a Japanese salaried worker spends 510 yen on average for lunch, 30% less than the average 20 years ago. It's no wonder the 500 yen "one-coin" lunch has become so popular. We go to Sendai City and step into the kitchens of restaurants to examine the hard work and ingenuity that makes it possible to serve one-coin lunches. The second half of this episode takes place in a gigantic district heating and cooling center situated beneath the high-rise city of west Shinjuku, Tokyo.
