Last fall I mentioned in a post that I had been underwhelmed, and indeed a little turned off, by our meal at Maison in late October 2019. But recently I received an email from Paris by Mouth describing a similar sounding visit in 2019, but then a lunch that was vastly improved in January 2023. Hopefully this link will work: https://parisbymouth.substack.com/p/maison
There’s also a great review here by Naf in November 2019: [Paris 11e] Maison by Sota Atsumi, excellent "traditional" French cuisine
Maybe it’s time to give Maison another try.
