Update - They are improving! New manager is making quite a difference. Hope it continues on the right track!
Original Review - I grew up on DD's in the Boston area where they are revered. Unfortunately this Las Vegas version is nothing like those east coast locales. Stale foods, order mixups, poor service...and I still go back for notalgic reasons. Even the coffee is burned to a crisp at times. Please Dunkin' headquarters in Quincy, MA - please fix this location. It rarely has business likely because of the complaints above.
Now homeless people are allowed to sit in the restaurant and stare at you. Very uncomfortable and completely unnecessary from such an established brand. I hope it has a chance to be reviewed before a closure I predict by the end of the he year. These employees probably wouldn't care.
