Setting
Brio's success might stem from the fact that any drink or snack you can think of will readily be available, no matter how absurd.
Regular Employees:
Rie (waitress)
Gwen (waiter)
Ren (counter-worker)
As for the owner of Brio... everyone knows him.... no one knows his name. Or maybe they do, but they aren't sure. After all, he gives a different one every time he's asked.
