My brother will be up in Utah over Christmas with 2 of his kids (they're adults) and the girlfriend of one of them. They'll be doing some skiing, and other things, and are looking for a restaurant that will be open on Christmas. I found this link for 2016, and that has some ok options, but I'm looking for maybe some other recommendations for him, if any of you have some good ideas.
