This is probably similar, but different. Because it's a coffee shop, the butterbeer is also an espresso drink. So coffee.
But without that it would be lots of butterscotch like coffee syrups and steamed milk.
Whereas, if I recall what I have seen and read, the Butterbeer at Universal is more of a creamy butterscotch soda?
But it would be similar.
And the butterscotch-esque flavor was actually really amazing.
