My husband and I were disappointed with Hollywood and Vine on our last trip. The food was fine, but the waitress practically ignored us and the atmosphere just isn't as great as other places. Sci-Fi dine in was much more fun at MGM.
At MK I would STRONGLY suggest Crystal Palace. Great food, beautiful restaurant, and Winnie the Pooh -- how can it go wrong?
We have eaten at Marrakesh in Morrocco and Biergarten in Germany and like both very much. If you want quiet away from the chaos, I would suggest Marrakesh. It was very quiet, not many kids, good food, nice service and a show at particular times. Biergarten is beautful inside in my opinion -- it looks like you are in a little village at night. However, it is very loud, especially during their show. Also be prepared to sit with strangers at your table, we had a family of 4 at our table with us. Great food though!
