For me the keenest pleasure is not the food nor the art but the countless prospects for a good walk; what one passes forms an architecture of sensual complexity. Leaving the Salon Saveurs we walked through the flea market along the Rue de Courcelles before forking back to pass the Arc de Triomphe  with its newsstands and trace a route down the Champs Elysées through the Jardin des Tuileries, none of which David had seen before.
