I went last year but will miss this year (I'm out of town or I would definately be there). It was fun. There were no players there but the coaches were there along with Pete & Terry.
There will be hundreds of wines there for tasting (be careful or you will end up drunk on your arse.). There is also some fresh brewed beer (what a difference).
The food is prepared by the Chef that does the Suite-Level Club (former Jack Daniels club) so it is awesome.
You'll also get a free riedel wine glass. These are fine wine glasses (probably the best in the world). Last year, they also gave you the opportunity to buy more glasses at a really low price (way under what you can find them for anywhere). I bought a few more for myself and then bought a set to give as a wedding present.
