For meals you have two choices;
1) there's a buffet close to the entrance of the lounge, to the right
2) there is a smallish sit-down restaurant, if you keep going past the bar, and almost all the way farthest from the entrance. There will be a sign stating: "Please wait to be seated". It's first come, first served; if fully occupied you should be given a wait time; if not full you just wait to be seated.

Depending on your preference, there is a further, small seating area even past the restaurant that's quite 'private' and nice, if not crowded.
