This Dunkin is probably the best one I've been to in the Vegas valley. The service is fast and friendly, and I've never had an issue with any of the food or drinks here. The original glazed are some of the best, and while I don't particularly care for some of the "specialty" doughnuts (i.e. Cookie dough and blueberry pie) the regular doughnuts are pretty good.
The hubby also always orders a large iced latte with mocha. While I don't particularly care for it, it is definitely a better deal than Starbucks!
