Starbucks, Krispy Kreme and Dunkin' Donuts have been expanding in the fast-growing India market, while Cafe Coffee Day, the country's biggest coffee chain, is going public.

Breakfast is the only U.S. restaurant meal time seeing an uptick in customer visits and Burger King was the No. 4 choice for "Breakfastarians", according to recent survey.
Burger King's comparable sales increased 6.2 percent, helped by new menu items such as Fiery Chicken Fries and the Extra Long Jalapeño Cheeseburger. Burger King opened 141 new restaurants during the three months ended Sept. 30.
