I was here today and enjoyed the location of this spot. It's nice to come here in the afternoon. While the menu doesn't denote what's vegan and is very dairy oriented, I was still happy with the choices and liked my meal, pictured above. The staff spoke only a little English. Prices are not exceptionally high considering the ambiance and presentation.
It's great that there's an all vegetarian place of this standard and the location is convenient enough to get to from Chaweng by motorbike / car. Good wi-fi is available. Overall, worth a visit if you're veg on Samui.
