The RiceTable at International Building serves all-you-can-eat Indonesian food. It's table service do you don't have to walk around
Try LeVeL 33 at MBFC. Nice ambience and great view overlooking the MBS area. Food is not bad as well.
Best go to normal restaurants.. is there a particular cuisine you both like?
Go to fine dining. There's a few available depending on your budget
Dun opt for buffet dinner. Go for fine dinning instead
Try any of the fine dining restaurants in hotels(:
elfuengo at jewel airport...
