Heading from London to Paris via Chunnel next week and need suggestions for dinner in area of Mandarin Oriental. Casual atmosphere a must---love true bistro food. Don't mind a walk or short cab ride. Verjus and Saturne come to mind, and I may be too picky to attempt Frenchie. Three nights needed! Best morning coffee and croissant ideas too si vous plait. Finally, best transport ideas from Gare du Nord to hotel and hotel to DeGaulle. Private car? Thanks in advance!
