Shake Shack IPO: Burger Chain Preparing Floatation: Scources

(Reuters) - Shake Shack, the fast-food restaurant chain famous for its hamburgers and milkshakes, is preparing to go public, seeking to tap stock market demand for popular casual dining companies, according to people familiar with the matter. After developing a cult following for its 'Shackburgers', 'flat-top' hot dogs and eponymous shakes, the company is now preparing to serve up its own shares to the public through an initial public offering (IPO), sources said on Friday.
