Have you tried EVERY flavour of Starbucks coffee? Each has it's own subtle taste- I really like the Latin American coffees from Starbucks like "Casi Cielo" or "Fincas de Chiapas." Both of those are limited edition, but if you have the chance, try also the Christmas Blend.
OH, and if you're in the bay area, check out some Ethiopian restaurants in the area- they have amazing coffee service.
And I agree with onesnowyowl.
