Four days in Paris - haven't been for several years
My personal responses (I know others would respond differently)
1. Le Cinq, l'Arpège, La Grande Cascade, l'Ambroisie, Pierre Gagnaire, Guy Savoy, (but none of them will be in the Eiffel tower)
2. Chez l'Ami Jean, La Régalade, Au Bon Accueil, Joséphine chez Dumonnet, Christophe, Le Chateaubriand, le Bistral, l'Auberge du Quincy
3. All of the above, plus Wally le Saharien in the 9th, Pasta e Basta in the 13th
See pics from all of them in my Picasa gallery -- picasaweb.google.com/zejulot
Be careful that many places are closed on weekends/mondays.
