I've been in Korea for a while and so I am not a typical tourist, I would say I know my way around pretty well and manage to use Korean sources to search for things I want to see or do. However, Mike's deep knowledge of hidden, sometimes not even listed food places and attractions completely amazed me. He's a knowledgeable and sociable guy who kept the tour fun while taking me to places I would never be able to find on my own. Keep up the great work Mike!
