L’Atelier de Joel Robuchon celebrated its third anniversary in Las Vegas on September 15. It bears remembering that we got our L’Atelier before New York got theirs, and ELV will stack the food of Steve Benjamin and Kamel Guechida up against anything the Big Apple can throw at us. Here is a sample of the Third Anniversary Special Tasting Menu — available throughout the month for $148.00 for eight courses of the food that made Robuchon famous — and that put Las Vegas in the cross-hairs of every gastronome in the world.
