The best unofficial site for DLP is this one. Unfortunately it does not have restaurant menus, although a few weeks ago ssomeone posted a review of all the park restaurants on the site's forum. There is a brief review for each hotel on the site. SimonV's new DLP book is out shortly and will include good hotel descriptions.
Thanks for the link Rob. Unfortunately, some parts of the site (mainly the bits I want!) haven't yet been translated into English. I only took German to GCSE level and that was 14 years ago - looks like I might have to get the old textbooks out!!
