They managed to fit us in just before Christmas on the Saturday. My mum has never seen this spectical before and she loved it. It was slightly disappointing that we weren't made aware of the Christmas menu when booking, but actually it was very nice. The starters were fab, the mains varied, and to be honest, we'd had more than enough by desert.
If you are ordering, consider ordering meat from the teppanyaki grill - my mum didn't and went for tofu. Whilst it really was lovely, she had to wait til everyone else round the grill had nearly finished, and she was actually full from eating all the teppanyaki bits - when the tofu arrived with noodles, there was not a chance she was going to eat that plate full! The kind waitress offered to box it up to take home if we wanted.
The service was very good as always, even considering the turn over - a waitress told me 800 people per day! And the value of the Christmas menu was great - £20 in the daytime for all courses.
If you are considering for Christmas next year, go for it, it is a very good meal, for a party, or for family. But book early.
