In 2010 Seppe started a new chapter in his professional life by launching Graanmarkt 13, together with business partners Tim Van Geloven and Ilse Cornelissens. The restaurant is situated on the lower floor of a lofty townhouse that contains three stories – shop, gallery and restaurant. Graanmarkt 13 is one of the top 3 best vegetable restaurants in the Benelux and among the top 25 best vegetable restaurants in the world selected by GaultMillau and We’re Smart. Seppe’s honest and healthy kitchen serves food that is both light and nourishing, raw and rich, herbal and enjoyable. For lunch or dinner, Graanmarkt 13 offers small appetizers or three and four-course menus in a relaxed atmosphere.
