The coffee in this bookstore café ($1.75; includes one refill) is prepared from an Italian brand called Miscela D'oro; it's medium-bodied and slightly acidic, and I love how the pump pot froths the surface. The café itself has a pleasant atmosphere: not too frenetic, but not overrun with all-day campers, either.
