No booze. The only place you can get alcohol in the MK is in BOG for dinner. I personally loved LeFou's Brew, but I have a major sweet tooth. My husband felt it was too sweet and would not get one again.
Incidentally, the same concoction is sold in California Adventure as Red's Apple Freeze and in Disneyland Park as Boysen Apple Freeze. Same. Darn. Drink.
We love jungle juice! But there's no apple juice or flavor at all in it. It's orange/guava/passion fruit. LeFou's brew is almost all frozen apple juice or apple-flavored something.
