This was one of my favorite ice cream bars when I came on exchange 8 years ago! The dwaeji bar (돼지바).
It's still around and is a comfort food of sorts.
It is a vanilla ice cream bar filled with strawberry sauce. It is covered with chocolate and then also crunchy chocolate pieces - some dark and some milk chocolate crunch pieces.
My neighborhood market has it for 400 won, but it's marked for sale at 800 won.
You can also buy it in any grocery store or convenience store. Usually the convenience stores have it for 2+1. :)
I wish I had a second one to eat.
