Feb 7 (Reuters) - Chipotle Mexican Grill Inc missed quarterly comparable sales expectations on Tuesday, in a sign that price hikes are taking a toll on demand for the restaurant's burritos and rice bowls.

Comparable sales at the California-based chain rose 5.6% in the fourth quarter ended Dec. 31, while analysts on average expected a 7.1% rise, according to Refinitiv IBES. (Reporting by Uday Sampath in Bengaluru; Editing by Josie Kao)
