Best food I've ever seen in a club, by far, is the Korean KAL lounges in Seoul. I was blown away by the selection. Large cubed chicken breast in a tasty sauce. breaded prawns, even sushi. Salads, multiple leaf and pasta salads. A huge delicious (not processed tasting) dessert selection. Whole grain fresh breads. The buffet went on and on.
I was amazed. Its worth a trip to korea to spend all day eating in the club.
