Le Sixties sur Marcoussis

06/06/2026: High-quality breads and pastries. An excellent old-fashioned flan.

29/05/2026: Last Wednesday, to my great surprise, I saw two large, traditional-style flans (€21). I thought to myself: strange, they usually only make them on weekends (according to one of the employees I'd seen earlier). Given their very dull appearance and the presence of steam, I didn't dare ask the waitress (a rather rushed woman in her fifties) if they were fresh. When I got home, the taste was off: pronounced acidity and a slightly refrigerated flavor. In my opinion, these pastries were made sometime between Saturday night and Sunday morning and hadn't been sold since. It's one of the first times I've thrown away part of a traditional flan. My opinion of Potier in general, where I've been going occasionally for several years. I've lived in Marcoussis for over 20 years. The pastries are well-made and taste great. Their galette des rois (king cake) is always excellent. As for the bread, especially the "Tradition" loaf, it has never lived up to its predecessor. Service: most of the time, the waiting customer doesn't seem to be a priority, and the tone is unprofessional. I think the counter staff are also responsible for storing the pastries. Conclusion: Mr. Potier makes very good pastries, but his bread is less convincing. However, everything related to customer service is subpar. The person in charge of this aspect seems to confuse customer with user. To top it all off, they give you a card after your purchase, dangling the promise of a trip if you leave a review. 🤦‍♂️
