This Korean restaurant has two branches, the other one on a side hutong from Nanluoguxiang and the other one near Beixinqiao subway. You can check both their addresses from their website: http://www.saveursdecoree.com.cn/
Being in the neighborhood, I visited this restaurant for the first time, and enjoyed it. Especially the crispy sauteed tofu was excellent. The dessert vegan chocolate mousse was good as well.
The restaurant is a bit more expensive but it's very stylish and a nice place. In the menu they have marked everything with a leaf if you can get it in a vegetarian/vegan version. Just remember to ask the dish without the egg on top. The staff was very attentive and spoke English. My companion is very allergic to fish and didn't have any trouble eating here, so I would imagine the vegetarian food actually is vegetarian, without lurking fish/crab sauce etc.
I will only give 3 cows as this is not a vegetarian restaurant, but that said, I could come here again if I'm browsing the Nanluoguxiang/Gulou area.Pros: good food, nice atmosphere, attentive staff
Cons: a bit expensive, not vegetarian
