I go to Dunkin' Donuts more than I probably should, but I enjoy the friendly faces when I go. The egg and cheese bagel sandwich I order is very basic, which is how I like it, and while I doubt that I'm getting a carmel latte with skim milk half the time I order it, I still go back again and again.
The major downside, besides the carmel lattes sometimes not being what they claim to be, is that there is an annoying guy who sometimes works the register. When he does, he says things like "love connection" and "that will be $500." It makes me want to tear out his voice box, or yell something inappropriate like "bring me back the nice, quiet Indian ladies, you dickhead!"
