Usually we have great food. Today however was not up to par. Our food came to the table luke warm and with the restaurant being as cold as it was, our food was cold in minutes. After we left the restaurant my husband told me there was a hair in the mashed potatoes. Had he told me while we were there I would have complained. Normally the food and temperature is great and we have never had an issue. Service was great and we had a party of 18.
