Ok, so it’s just another Dunkin’ joint right? Wrong. This is DD in Da Riva. And it creeps me the eff out. Homeless people and other transients lineup along the window by the front door. The bathroom requires a buzz from the cashier to gain entry. Every time I go, throngs of morbidly obese customers have plunked their overflowing bottoms on seats that, by all rights, should collapse under the pressure. Spend more than 5 minutes inside and you’ll walk out smelling like a sausage, egg and cheese that was just dunked in a pail of coffee.
