It looks fine to me.
I even love the experience of buying Butterbeer. Standing in line outside of the cart, seeing people ahead of me enjoying their first taste and watching their faces light up. Then when its my turn I hope my extra friendly demeanor will grant me some extra foam on top of my drink.
I understand Butterbeer had huge expectations to live up to and IMO it exceeded them. Its hands down the best theme park drink I've ever experienced.
I've been to Cars land more than a dozen times and have only bought their frozen drink once. Its not very good. I dont like the foam or the taste and to hear that its going to be the signature drink of LeFou's makes me a bit sad.
I know there will be pundits who cry fowl over the fact that Disney's drink is healthier, but if I wanted something healthy to drink I'd go to Whole Foods.
When I pay $5.00 for a signature drink I want something that is delicious and Universal has clearly delivered on these expectations while Disney has not.
We knew that Disney was making this Tavern for awhile, HP or not.
What would you have liked to see in the drink?
Walmart quality? They look nice to me! Also, I highly doubt they would allow glass or ceramic at the MK.
I bet its going to be a hit, no matter what it ends up tasting like.
