Go to Dunkin Donuts. It's cheaper and it tastes better. The only thing is that it's not trendy but nobody will scoff at you for having an Android phone.
As a New Englander I am probably committing sacrilege by saying this, but literally
everything about Dunkin Donuts sucks. The food is horrible. The donuts are god awful. And the coffee is weaker than weak. It is the place to go if you like a glass of sweet cream with a splash of brown water.
Now I'm not saying Starbucks is the best, because it is not (local places near me serve better coffee/espresso for less). But it is better than Dunks at every aspect of the coffee house experience, and considering how many stores it has it is pretty impressive how uniform their drinks taste from shop to shop (Occassional bad barista excepted). FWIW - I rarely if ever drink SB's speacialty drinks. But when I do go there I usually go for black iced coffee or, if its a rough morning, a black iced americano (coffee+espresso).
As for dunks not being trendy - that is probably true if you live south of Connecticut. Up in New England you would think Dunks is a religion from the way most people revere it. Perhaps it was good at one time. But it is just awful now. New Englanders seem to have a fondness for juding restaurants based on what they used to be instead of what they are now. Kelly's Roast Beef is another awful restaurant that just about every New Englander raves about.
