I had a great dining experience at Kiseki. We went for Sunday lunch and I would say it is very worth it. At $28.90 ++ for adults for sunday buffet at Orchard area, I think it is a steal.
Choices are good- from salmon sashimi, octopus sashimi to fried tempura, grilled salmon head, mini steamboat and desserts.
Service is prompt in clearing our plates and we had an enjoyable lunch :)
