Dining in Las Vegas: Part 1 in Southwest & Western States: Dining Posted July 30, 2009 u.e., don't worry. I'll be in LV next week. I can have dinner with Robert for you. Robert, just e-mail me. FYI Robuchon at the Mansion will be closed during that time, but L'Atelier will be open. Guy Savoy should be re-opening in Aug. Alex should be open as well. Dining alone does have its merits, M&M. Nothing gets in the way between you and the food.
