Wow. This place is one of a kind in Chiang Mai. We all know Thailand is not famous for chocolates of any kind, but this place is really awesome. Various kinds of chocolates and bonbons are made at this companies factory in Bangkok, and now Chiang Mai has a branch. It's not cheap of course, but who cares because it's the only one of it's kind and it's real good! You can select bonbons or truffles or chocolates form a display case, where they pack them for you in a box. Most go for like 12 baht a piece. There are a few tables where you can order coffees and hot and cold chocolate drinks. These go for like 45-55 baht and this includes two chocolate bonbons per cup/glass.
The place is on Bamrungrat Road, near the British Council, but on the other side of the road, close to the intersection with Kaew Nawarat road. Some people may know Bamrungrat Road as the Sayuri Road. ;-)
