We just came back from Jedu-do and would like to highly recommend Mr.Kim Taxi service. We used his Taxi service for 2 full days tour and was very, very happy with Mr.Kim service and knowledge.
We originally found Mr.Won service (tripadvisor.com/ShowTopic-g983296-i13236-k39…) but he was fully booked and he recommended Mr.Kim to us.
Mr.Kim speaks acceptable English, so simple English conversation was not a problem. He took a lot of nice photos for us and could use DSLR camera pretty well.
We were doing one of the Olle trail and he dropped us at a starting point and picked us up on the other ending point. Instead of waiting in his taxi, he walked a little from the ending point to take a photo for us with the Oedolgae rock background.
The trip planning was very easy, we gave him a list of places we wanted to go and he drew up the routes for our 2 days tour. He also recommended a few other places we didn't know and some local farms we drove pass.
He also took us to two very nice restaurants and we found it very delicious and cheap. First one was serving the black pork and they also served this very delicious sweet potato noodle soup. Second one was this seafood restaurant by the sea, 45000 won fed 3 of us (incl. Mr.Kim), they served raw abalone but we had the option to cook the abalone in the seafood hotpot instead. We invited Mr.Kim to have lunch with us and it was very comfortable eating with him. He would tell us how to eat like a Korean.
PS: He also speaks very well Japanese.Edited: 7:35 pm, August 11, 2014
