Same-store sales rise at Chipotle restaurants

Sales at established Chipotle restaurants turned positive last month, potentially a sign that the burrito chain may be starting to recover from a food safety scare.

The Denver company said Tuesday that sales at established stores jumped 14.7 percent in December. They fell 1.4 percent in November and fell 20.2 percent in October.

The rebound in the final month of the year eclipsed a disappointing outlook for the entire fourth quarter.
