To enjoy gourmet food in France you don’t have to sell your kidney. Just go to supermarket or even better to one of the food markets where farmers sell fresh produce and you will get away with a gourmet meal at a fraction of cost of what it would cost in a restaurant.
Delicacies to consider:
Foie gras with bitter orange confiture
Burrata buffalo
Pear/cheese combinations
Cured meats/melon/apricot/peach/berries/grapes combinations
Baguette and desserts from the closest boulangerie/patisserie
Local yogurts in glass jars
A touch of freshness with fruits and vegetables from the market
