I hand't tried krispy kreme before coming to korea and I loved it. They look really cute an appetizing, specially now with the strawberries season! The price is around 1,700 for a simple one with a strawberry, so a bit more pricey than dunkin donuts.
I also heard from people in California that they are much better in the states, as they bake them in front of you and are tastier. Now I cant wait to try those ones!
