I have come here a handful of times and I'm not much of a Dunkin' Donuts person but by rating off pure service alone I can say I'm a fan. The employees who work here are very friendly and helpful.
The few times I've been here I got the Dunkaccino every time for my drink.
But as for munches my favorite is the Big N Toasted, toast sandwich with bacon, egg, and cheese. I love the heavyness to it so if that's not your thing don't get it. I also had the Chicken Salad Sandwich, it's on croissant which is a plus but the chicken is chopped and mixed in with other ingredients. The Egg White Flatbread was so bland but good for its low calorie effect.
The only other Dunkin' I have been to is the one by W. Charleston on my way out there and that is walk in only. Here, there's a drive thru.
