A repeat offender is the lone low performer in this week's Kitchen Cops report. Nesbitt's Jackass Saloon in Calabash lost three points because raw hamburger was stored on the same shelf with lettuce and plastic cups were being used as scoops. There were live roaches in the kitchen and in cabinets at the wait station. Sour cream was out of date. And several things need cleaning. Ten violations in all and a score of 87 for Nesbitt's Jackass Saloon. One Wilmington restaurant made this week's high performers list. Top honors belong to Le Catalan at 224 South Water Street downtown. No violations and a perfect 100.
