Starbucks coffee. Tastes just like it does at any of the other million or so starbucks on the planet. Barrista doesn't really do anything other than punch buttons on the machine and steam milk, so there isn't really a lot to mess up.
Service on the other hand, is variable, and this place seems to have found its rhythm. Long lines in the morning move quickly, staff are friendly and seem to have a handle on what's going on.
Prepared food is pretty terrible, but then who goes to a Starbucks expecting something good to eat?
