I was wondering if there is an equivalent to the famous Grey Goose Slushie sold in Epcot to be found somewhere in California Adventure. It is a lemony flavored frozen drink with vodka in it!
Not to my knowledge... I think there are special drinks at the Mad Tea Party that are alcoholic but I don't know if they are similar to what you are looking for. DCA is much more wine focused (reflecting CA culture). But your drink sounds quite yummy!
They do not have anything like that specifically. If you want to try something different, they have a Vodka (Skyy)Pomegranate Limeade at the Cozy Cone in Cars Land...Yummy!
I am a huge fan of the Grey Goose Slush from EPCOT's France. I have never seen anything like it at DLR. On the off chance you happen to find something similar there, let me know!
