Starbucks over DD by far as I like dark coffee and feel happiest when I have my double tall latte. I prefer Peet's to Starbucks.
I'm pretty addicted. I now have one of those fancy digital espresso makers (purchased at Starbucks) that grinds the beans when you press a button, makes espressos and regular coffee as directed, and then pushes the grounds into a special container and periodically to clean it or give it water or beans. I order Zabar's Double Dark Espresso beans online (they somehow arrive the next day with regular shipping) and am in heaven (at least after I wake up).
