In December of last year, Moutarde closed "for renovations," never to re-open. The deathwatch had been on for some time by that point, as the owners of the French restaurant, on Fifth and Carroll, had changed up the menu, oddly decided to only be open during the weekends, and last March put the space up for rent.
Last month word got around that an outpost of Le Pain Quotidien would be moving into the space, and sure enough, the rumor was confirmed and constrution has begun.
The storefront's exterior has gotten a coat of white paint, and as expected it looks like the company has decided to keep the facade's other details intact (which would make sense, considering how French it already looks). On the inside, it's still in the process of being gutted.
As is usually the case with successful chains, the buildout shouldn't take much time at all.
