Four of them to be precise. That's what the Dunkin' Donuts Grilled Cheese Flatbread will cost you. Naturally, you'd would think that the simple household staple would have a little extra kick to it. But you'd be disappointed to find that the menu item is no more then a glorified grilled cheese sandwhich. It's not that it was bad. I might go as far as to call it a tasty treat. But definitely not worth the dough.
