Some 40 New York City operators have filed a $150 million lawsuit challenging the city's health department letter grades. In healthcare news, the mandated coverage that will go into effect soon may not have the desired impact, since a loophole allows employers to offer staff high-priced options that they may not be able to afford. The Cheesecake Factory is planning to grow again. On the menu, high-end chefs are using lighter ingredients to serve consumer trends for healthful options. And Amtrak has enlisted leading chefs to revamp the food served on its trains.
