Locavores, listen up! One of our favorite gastropubs and home of the “Secret Chef,” Jimmy's No. 43, is hosting a “100-mile dinner” Sunday night. The meal, in which all the materials come from within a 100-mile radius of Jimmy's, benefits Slow Foods in Schools programs throughout the city, so that the eaters of tomorrow can be inculcated with Haute Barnyard orthodoxies. Chef Philip Kirschen-Clark has a big menu all planned out, including “surf and turf” with venison and yellowfin tuna, braised mutton cheeks, roasted duck hearts and livers, Tropia Onions “Agrodulce,” and so on, all accompanied by local ciders and wines. There are two seatings: at 6:00 p.m. or 8:30 p.m. Tickets are available through Brown Paper Tickets for $85 (for Slow Food N.Y. members) and $105 (nonmembers). But it's for a good cause: your physical satisfaction.
