I once asked a waiter at Amethyst for a small mocha and gestured a tiny cup with my fingers. He brought me a cup the exact size I showed him. At first I thought he was making fun of me but I loved the tiny cup of mocha. It was hardly enough but that's what I ended up ordering the next couple of times I went there. I'm sure it's called something other than mini mocha though. There's something about miniatures, isn't there?
