I went here for my birthday, and I had a wonderful time!
As you can guess, booking early is required, however I only booked 2 months in advance (not sure if 2 months is early?). My birthday fell on an early weekday, and I also preferred the earliest reservation, 6pm, so I was lucky in that it wasn't one of the most popular types of bookings! I just sent an e-mail through the website and Rebecca came back straight away to me.
Even though it was a weekday, it was still full by the end of the night. I had a great time; the food was amazing (as expected!), and the service, especially from the head waiter, was excellent. We also opted for the pacific oysters, well worth it!
My mother doesn't like cold soups, so we requested for her soup to be changed, and it was done straight away! She couldn't have been happier.
It's really a great dining experience, and I can't wait to go again!
