Las Vegas
Tucked into a strip mall near the airport lies an unassuming storefront that has become a destination for epicurean high rollers. Artisanal Foods (2275 E. Sunset Rd.; 702/436-4252) is the brainchild of Brett Ottolenghi, who made his name as an importer of rare truffles while still in boarding school. More than a decade later, he procures obscure ingredients for the most in-demand restaurants on the Strip and also sells them at wholesale prices in his grocery. Among the luxury items lining the shelves: argan oil, Korean black garlic, and edible gold, not to mention lobes of foie gras, bien sûr.
