I know that chain of puff stores. Their durian puffs are tasty, but I agree with you that the flavour is very mild. The thing about those puffs are that even people who normally don't like durian can appreciate them, and you may fall into that category.

There are different places you can get durian puffs where the filling is basically pure durian. Of course, unless you love durian you're not going to appreciate them.
