Just came back from a highly-anticipated dinner at Daigo but sadly have to report that I was highly disappointed. I had the ume course at 15,000 yen (there are 2 more options at 17k & 19k yen, and all these prices are before tax, service and drinks), and the presumably high quality ingredients notwithstanding, the whole meal pales in comparison to any of the shojin-ryori meals I've had in Kyoto (adjacent to temples). Those meals were a lot more intricate, interesting and tasty, a veritable feast for the eyes and palate. The Daigo meal, in comparison, was prosaic at best and in fact left my mouth with an unpleasant after taste. The private (interior) room, while tastefully decorated, did not look out to anything interesting and did not have tatami mats on the floor. Service was good but not outstanding.

By the way, I told them not to use dashi when I first made the reservation. Normally they do use dashi, so vegetarians beware!
