Looking for a place to find yuzu products, unfourtanatly K-Mart have not been good enough for that cause in last visits. Reading about Isse workshop, and it seems that i might find there yuzu powder and juice, at least one article says that Herme buys it from them, or so :-)
But the website is not working, and i can't find helpful details to determine opening hours etc..
And regarding Isse Izakaya - interesting place ? Might be a good option for us in middle of Louvre day, and a variation from French food.. Or maybe take the short metro ride to Toyo..
