What about the availability of food and non-alcoholic beverages? Are there places to sit or is it just a standing room only establishment? Permitted or not, are children welcome? (That is, do they stand out like sore thumbs?) When does AC open and how many shows are there during the night? Is it loud and obnoxious like other "clubs?"
In other words, as a non-drinking guy with kids ages 6-12, should I even give it a try?
I first went to AC with a group of forum members sans young children a few years ago, and both my 18 year old daughter and I thought it would be perfectly appropriate for MY then 11 year old. However, my husband uses a lot of puns and wordplay (including double entendre) on an almost daily basis, so The Son was used to it. He also has a sister who is ten years older, and she has never "talked down" to him. (and apparently hasn't always been careful about her language or the movies she watches around him

)
So there was nothing there that he hasn't heard before, and he was able to enjoy an evening there without ruining a more adult evening for others. The last time I was there, I wanted to stay for Hoopla, so my husband did take him back to our hotel, while I continued to party with mkt, PhotoDave, Master Yoda & bride, Foxfire, sillyspook, disneytati, and several others.
I don't think it would be appropriate for the 6 year old, however, only because he/she would get bored, and might start asking a lot of questions, which might annoy other guests.
As I mentioned, I know MY children, and know what sort of humor would appeal to them. (The Son loves the Black Adder series, especially the Private Plane episode, so anyone familiar with both the series and the AC would understand that he really can appreciate the club.) I also waited 18 years before I had a chance to check it out myself, and preview it before taking him there.
Oh, as far as your other question goes, it is set up like a private club, with chairs, etc with the bar being to one side. You do not have to sit at the bar, but make sure you watch those who do. The Library is set up like a nightclub, with numerous tables and chairs.
And that's all I'm going to say about that.
