This is a Shirogoma ramen at Kodawari Yokocho (in Paris), a limited edition they do for only 2 weeks.

Here is how they describe it:

Cashew nut and white sesame cream, ginger and garlic, emulsified chicken broth from the Luteau farm. Chashu of Simmental beef, an Austrian breed with a lot of flavor and a very beautiful texture to discover. Chashu of Basque pork loin cooked at a very low temperature for 18 hours from Peio Errecart in Saint-Jean-Pied-de-Port. In the chef's version [that's what I took] you will find Ra-yu for a spicy kick. The natural Umami of our dashi, soy, miso, combined with the creaminess of sesame.
