It's a difficult choice. For me Christmas just wouldn't be the same without the traditional dinner so I would probably opt for that. Have you asked if there are alternative starters and desserts? Usually there are as alot of people don't like Christmas pudding and mince pies. In last year's winter brochure I'm sure that there were menus printed for Christmas dinners as I remember reading it and thinking that the cost seemed reasonable - don't recall seeing it in this years brochure though - not much help I know! Unless someone might have last years brochure still?
