My husband and I will be spending Christmas Eve in Vienna. We understand that many shops, restaurants, etc. close early that day as most residents celebrate with family. We're looking for a recommendation for dinner reservations. I have noticed that lots of hotels have fancy dinners, but we were hoping for something a little less formal. We are adventurous eaters, so all types of cuisine are appreciated.
Here's a link to a list of coffeehouses and restaurants open on 12/24.
