Dunkin Donuts has pretty good coffee but nothing can touch starbucks. I practically live there. For spring break I went to hilton head where there (for some reason) are no starbucks... so the entire ride home I was searching for one... needed my fix.
I always order a Grande Double Blended Raspberry Coffee Frapachino without whip cream. Custom drink, but NOTHING can touch it. Try it if you never have. I swear they'll one day add it to the menu calling it the Harry Special or something. It's amazing. <3
