Just ran into Seurre's former caissière at Les Papilles Gourmandes, who told me the good news:
Seurre is reopening, in the old address on rue des Martyrs.
No it won't be a Monop Beauté after all, probably because everyone in the hood bitched to high heaven about Monop Beauté replacing Seurre. One of the legal conditions for Monop to replace the old store was that it had to offer artisanat products, which Monop claimed to do, in the form of a nail bar. Am not making this up.
The opening is scheduled for the fall. Will keep you posted.
