Just finished my visit to CPT. We at at Five Flies, Belthazar, Wakame (lunch), Codfather and Bo Kaap Kombuis.

Five Flies was excellent, and by far the best meal we had.
Bo Kaap Kombuis was a very good Cape Malay meal with very hospitable service with fantastic views high up in Bo Kaap overlooking Table mountain.
Codfather was pretty good. Shellfish was great, kingklip was only ok (no butterfish available...)
Wakame was good, nice setting, but sushi in South Africa just isn't all that exciting. They don't have nearly the variety of fish that you can get in the U.S.
Belthazar was ok. Seafood very expensive but pretty good. Wasn't overly impressed with the (rump) steak. I'll stick to the top steakhouses in NY for beef... (except maybe when in Buenos Aires!) Very extensive wine list though, and lots of choices by the glass.
