It's funny that I have a post for this, because while I am a nerd, we won't really be doing anything HP related. Maybe I'll have a Butterbeer Frappuccino? If I have one I'll post the picture below. Want one too? Head on over to your nearest Starbucks, ask for a
Breve coffee frapp with a shot of toffee nut and a shot of caramel syrup.
OK, you don't have to ask for it breve, but it's good. Be sure to give them a good wizard name while you're at it.
Then you can come back here and thank me.
