I don't know why the food does not stay hot when served. It's good when we first get it but sure cools off fast! We stop at this Carl's everytime we go to San Diego & Back as it is easy on easy off the 101. WE stopped on Dec. 28th & what wasn't appealling was a homeless man at a corner table when you come in the door. Don't know if he ordered anything or not but when my husband went into the men's restroom, he was there "washing up"! I don't think this is appropriate in this type of establishment!
