We went here twice in September 2012. Ghent must be one of the best cities of its size in Europe for vegans but we found Cuisine Ouverte the best quality food we had anywhere in the city in the week we were there. While the all you can eat buffets at other locations are cheap and delicious, CO is a proper small restaurant with a limited but high quality selection which changes about once a week. We found the staff very vegan-aware, able to advise (in English) what was and wasn't OK, and what could be adapted, and everything we had was clearly vegan. There were two options on each course that were vegan or could be made vegan, I think we had all of them between us over the 2 visits - and all excellent. Highlights were an amazing Chervil Soup with Dumplings and a really good chocolate cake. Nice atmosphere and fairly central.
