Can delivery sustain the turnaround at McDonald's (NYSE: MCD)? The burger giant plans to expand its current delivery program in the U.S. from 2,000 restaurants to 3,500 by the end of this month. McDonald's has partnered with Uber Technologies, Inc.'s UberEATS service to reach this ambitious target. The initiative to push burgers to the doorsteps of its core customers is part of its attempt to reinvent itself as a more contemporary burger chain.
