We've eaten here 3 times and after each time our perspective has changed.
The first time we visited we were seated in a back room overlooking nothing at all. There were Chinese tourists wandering around and making unpleasant noise. Service was rushed and against this context the food felt a bit overpriced, although it did taste delicious. We went away feeling slightly disappointed.
The second time we were lucky.. it was a quiet day and we seemed to be the only people there. We were ushered into presumably the best room, which to our delight overlooked a magnificent zen garden complete with koi fish and floating lotuses. Amazing the power of a space - in this serene and meditatively beautiful place the food felt exquisite and we gladly paid the price tag. We couldn't wait to go back.
Last week we tried our luck for a third time and to our dismay were seated in the same back room as the first time. The experience again felt so-so and the value for money did not feel to be there.
Not sure if they accept seat requests but if you're feeling a bit daring it may be worth asking when you reserve.

Cons: Back rooms are boring, Price is not cheap vs quantity of food
