First off I would like to say J-E-T-S Jets Jets Jets to you, cdtommie!
It is very unlikely that MK will ever serve alcohol. Supposedly, Walt didn't think too highly of alcohol or those who enjoy it and, at his request, vowed to never allow alcohol in the MK.

But I have heard rumors of alcohol being served at private parties, where MK is closed to the general public. Not sure if that is true or not.
With that being said, at one point a Beauty and the Beast themed restaurant was in the plans for the FL Expansion (not sure if it still is

). If it still is in the plans, and is still planned to be a French restaurant, I can't see how they can justify not serving wine. French cuisine and wine kind of go hand-in-hand.
