The James Beard Foundation has, in the past, been critiqued for what some saw as a bias against Los Angeles. This year the JBF has been making it up to us, first by naming Nancy Silverton Chef of the Year, and now by bringing a big Beard bash to Vibiana this Friday. For $275 a seat (or a modest $2,500 table), diners can enjoy a reception and sit-down dinner featuring the culinary mastery of chefs including Aarón Sánchez, Mozza’s Nancy Silverton and Matt Molina, Ori Menashe of Bestia, République’s Walter Manzke, Vinny Dotolo of Animal, Ari Taymor of Alma, and host chef Neal Fraser, who will soon open his long-awaited Redbird in the downtown cathedral.
