I had some cakes frm this shop and I really like them. My most favorite is chocolate pudding which is so good and cheap, only 65 baht.

Actually they are pretty famous for chou creme but I prefer cakes more.
At some branch like Future Park Rangsit (basement floor), you can taste so many cakes before you make decision which I think it's really good way for marketing.
Try some...and you will fine one that you like :)
