Kanda Tokyo

I will be visiting Tokyo for the first time next month. I want to do one high end Kaiseki, and managed to get a reservation at Kanda. Anyone been? Is it worth it? In researching Kaisekis, Ishikawa looked most appealing but I was unable to get a reservation.

I like Ishikawa a lot, but never visited Kanda. Here are two reviews for Kanda and their views are quite different.
