Christmas lunch in Cape Town

Hi,

I will be on honeymoon in Cape Town over Christmas, staying at Ellerman House and trying to decide the best places for Christmas lunch.

The hotel has provisionally booked each of Reubens at the One&Only (which is a buffet so I feel could risk the quality?), Azure at the 12 Apostles and Planet at Mount Nelson (I am worried this may be a bit stuffy but the food looks very good?).

Are any of these a clear winner to you, or would you choose a different option?

Price is not an issue - we would like somewhere special.
