This place is fantastic! They have a little satellite stand in the atrium under the Rainier Tower and I am a devout customer (along with my entire office). I never knew I liked mochas...the ones I have tried have been syrupy and bitter, so I stuck with flavored lattes. But the Dilettante changed all that. They use real molten chocolate and they have several different types, ranging from extra-dark (70-something percent) to the creamy perfection of milk and white chocolate. It really is unlike any other espresso drink out there and a MUST if you are a chocolate fan. Just make sure they make it hot enough...their baristas are careful not to burn you, so the drinks can be a bit cooler than I'm used to.
