On my flight back to LHR on LH from CPT I used the SAA first class lounge in JNB. It's not the fanciest, hippest lounge I've been to but the dinner service there is the best I've seen in any lounge. The food and wines were so good I was sorely tempted to ask for seconds and skip the meal onboard.
I wish more airlines had friendly and helpful staff in their lounges.
