When I check into Paris's Mandarin Oriental, I never want to leave my room; some days, I barely do. I just stay in my robe, dining grandly on the stellar room service. Mornings bring city-themed breakfasts. A dashimaki omelette and grilled sea bream make up the Tokyo repast. Eggs, coffee, and a pastrami sandwich? New York, of course. The Parisian petit dejeuner features croissants, Bigorre ham, and champagne. Midday is for international grazing. At midnight, I call down for a snack: a vibrantly spiced nasi goreng (Indonesian fried rice) and the ultimate nightcap, a bittersweet chocolate mousse. I sleep like a baby.
