Did the Chocolate Bar Afternoon tea with some friends before Christmas. Wow!!
It's not cheap, we paid $75 each but the desserts are absolutely amazing. It's a whole table of just chocolates, cakes and slices. You also have the standard afternoon tea where you get sandwiches, quiches and scones. Tea, coffee and hot chocolate are unlimited.
Definitely coming back :)

Approximate cost: $75

The Tiffin Afternoon tea served is delightful, with complimentary tea or coffee you are able to choose from a "traditional" or "chocolate indulgence" tiffin tea which includes sandwich fingers, scones and jam, and an assortment of petit fours. It is reasonably priced and provides for a great experience or special treat with girlfriends. It's also great because you can choose your tiffin tea individually so one person can have chocolate, and the other traditional.

Approximate cost: $50
