I have to say that I am haing little luck but here is what I have so far.

Ritz - fully booked
Marriot & Four Seasons - have not finalised their xmas menu / costs etc but should have done by next week, maybe.
Movenpicks are doing a special dinner rather than lunch ad will still take reservations. Cost QR135
Ramada are doing xmas lunch and is QR110 plus 17% service charge per person. They are nor taking reservations yet, maybe next week.

Soory not much but it is a start.
