Yeah, yeah, you'll pick up all kinds of helpful kitchen tips at Sanctuary's "Lunch & Learn" series — which celebrated its 10th anniversary this year — but the truth is, if you're going to shell out $125 for a cooking lesson, it'd better be from the likes of Robert Irvine. And it just might be. Each summer, Sanctuary executive chef Beau MacMillan invites a few of his Food Network pals out for a posh little summer vacay and a lap around the kitchen — and you're invited, too. This past summer, Irvine hit town, along with Marcus Samuelsson, and the lineup always includes cream-of-the-crop local chefs, as well. The 2012 schedule will show up on Sanctuary's website next spring — and space is limited.
