We flew Turkish Airlines from Johannesburg to Istanbul on April 4, 2012.
This was our first experience with Business Class on TK. The business class section had less than 30 seats. We were pleasantly surprised to be greeted by a SKY Chef in full uniform as we were boarding the plane. He came to talk to each passenger personally, going over the menu with everyone and offering some very helpful comments on the dishes being served - proudly serving the best of Turkish food- as the menu said.

The food was excellent however the service proved to be less than stellar. There were no less than 6 flight attendants (including the Sky Chef) dedicated to the Business Cabin alone and yet the service was a hit and miss proposition. The cabin staff was scurrying around and seemed to be on the go constantly and yet when we asked for an after dinner scotch, it never arrived.

A word of caution: we were seated in the last row of the business section next to the galley and found it to be very disruptive as we were trying to get some sleep. Dishes were clattering around and the staff was talking constantly and loudly. Be warned: avoid proximity to the galley

Otherwise Business Class on Turkish Airlines was a pleasant, gourmet experience.
