Depends on what type of food you all like, who is picky and who is not. Our favorite by far is LeCellier. After that, we would choose Biergarten (a fun time for all-- a buffet with great music, dancing, etc.). We hope to try the Italian restaurant one of these days but could not fit it in during our last trip. We also like Rose & Crown.
I love Restaurant Merrakesh!!! Also I remember the waiter's at Alfredo's (now Tutto Italia) being very cute and flirty- I think it's part of teir job description
I would give a vote for 9 Dragons. I know it is not everyone's favorite. But it's usually not packed, which means you are not right on top of everyone else, and they definitely don't rush you out the door.
