Chipotle Mexican Grill reported mixed quarterly results, with shares dropping 7% after same-store sales growth fell short of expectations. The company posted a net income of $378.4 million, or 28 cents per share, while revenue reached $2.79 billion, below the anticipated $2.82 billion. Despite a 6% rise in same-store sales and a 3.3% increase in restaurant traffic, food costs rose due to larger portion sizes following customer feedback. Chipotle plans to open 285 to 315 new locations this year, with a focus on restaurants featuring a "Chipotlane" for online order pickups.
