Some friends had raved about Zen but I was a bit disappointed. For sure, it's a beautiful setting with a large open space, views over Kigali and grass roof. However considering it was almost empty I ended up squashed by a pillar!! I had a Thai green curry, a favourite dish of mine, and it was a "green curry" but not one I would recognise. It was nice enough and I enjoyed it but I wouldn't order it again. Definitely fusion food, not Chinese, Japanese or SE Asian. I think the meat eaters fared better. For authentic Chinese (or Japanese) food there are better places in Kigali I think.
