Further to Rodger Fs reply re Saumur, this little aerodrome is one of my favourite French stops. If time is limited, you don't even have to go into town.
Le Clos Des Benedictins, 5 minutes walk across the grass, if the aeromodellers are not about (if they are, it's only a couple of minutes longer by road), does a very good lunch, either dans la salle or sur la terrasse with a magnificent view across the town to the chateau.
Bon vol at bon appetit!
