Is there anything Louisa Chu can't do? Not only has her prerecorded run as guest judge for Battle Zucchini just finished, but she's taking a break from a summerlong cheffing stint on a fishing boat in Sitka, Alaska, to serve as fixer for Anthony Bourdain and the No Reservations production team, in town today through early next week to film the long-awaited Chicago episode. Louisa, who made a memorable appearance in the first season's Paris episode (and many on Gourmet's Diary of a Foodie) will be escorting Bourdain and crew to L20, Calumet Fisheries, and Burt's Place, among other locations--including a visit to the Tom Tom Tamale factory and Fat Johnnie's with the distinguished Peter Engler.
