Since you guys start to get into semantics and definitions, to me "open" is like "pregnant", you are or you're not.
They're no such thing as half-open nor half-pregnant so if a restaurant is open, it must serve food. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />

And for the record my pick is end of December, and if I have have to pick a date, it'll be Dec 28.
