Mornyville,
Oh la la! how fun! dream to go there before I turn, um, very old and don't have any teeth!
How much does he know about the Tour d'Argent? Could tell him to meet you at le Rotisserie du Beaujolais, unless he would google it & find out its connection to TdA.
Otherwise, le Coupe Chou, 11 Rue de Lanneau is lovely/anniversary-ish and near.
