I found other people's reviews and decided to go there for lunch with my husband. It was well over my expectation even after reading those great reviews. They had a lunch course from EUR18.50, but we chose EUR32 course where we could choose one from a few options in each of appetiser, main and dessert. Each dish was enjoyable with perfect combination of taste of different fresh ingredients also with visually pleasing and artistic presentations. Wines were also surprisingly reasonable. Great cost performance.
I made a reservation 4 days before, and we got a table on the terrace with a beautiful view of the town and neighbour farmland. I strongly recommend you to make a reservation in advance as I noticed tables on the terrace were fully booked.
When we visit Provence again, I will definitely come back at La Maison de Celou!
