Right in the heart of Moustiers-Sainte-Marie above the river lies La Treille Muscate. The perfect location for a romantic meal.
In the existing feedbacks you can either read it's one of the best restaurant around or some sad experiences, but in full honesty this place is worth going. Quality / price wise you can't be disappointed. A menu (starter + main course or main course + dessert for 29.50€) of that quality remain to be seen. It's not the best food I had, but I didn't expect a 3 star Michelin either. It's a great restaurant in a gorgeous town and your belly will be more than happy for your time spent there.
Furthermore, if I were you and was planning a stay over, you can look up for the "Maison de Jules" which are the rooms rent by the same owner of the restaurant (literally next door), spacious, squeaky clean, modern and quiet and all of that at a reasonable price.
I can only recommend any of the above.
