A worker grills hamburger patties at a fryer in the kitchen of the first Shake Shack burger restaurant to open in Moscow, Russia, on Tuesday, Dec. 24, 2013. The New York burger joint known for its queues will sell ShackBurgers for 235 rubles ($7.15), about 50 percent more than in New York and almost triple the price of a local Big Mac.
