I had this for dinner. Dontkatsu is a very common dish you can find in Korea though is not a Korean food. Specially my friends and I came across a good place with donkatsu with spring onion. It came with mustard sauce at the bottom, a bowl of rice, mini udon and some side dishes. The mustard sauce and spring onion play a perfect role in calming down the grease of the fries. This is my first encounter of this unique food. Love this!
