The owner/sushi chef was the original chef at Shijo's about 17 years ago(when it was actually good). He is from Japan and his dishes reflect traditional Kyoto style food.
Food: I had Kinpira Gobo (burdock), suimono soup (clear broth with shitakes and fish), spinach ohitashi, Uni, Yamakake (tuna with japanese potato) and a bbq chicken dish with lotus, shitakes and other ingredients that I don't even know (this was special dish that he made for me- not on the menu). ALL were very good. But, if I had to pick a favourite I would definitely say the suimono and the bbq chicken dish. He is very flexible and creates new dishes for you if you ask. I didn't order omakase, but I think next time I go I will.
Service: I originally was sitting at a table until I was coaxed by someone to sit at the bar. I like sitting at the bar because you are able to converse with the owner and talk about food!
Value: I think that it is very reasonable. You receive quality unique dishes for a fraction of the price. I think this is due to low overhead costs. Some reviewers said it was a rip off... well if you are comparing it to the mass of Korean ran restaurants then yes, it is. But, realistically it is not for what you are getting!
Ambiance: It isn't somewhere that you would go for a nice ambiance, just good food.
