'Starbucks vs.  Dunkin' Donuts. Starbucks offers a more extensive menu and more product customization, which is accompanied by a comfortable and quiet environment with free wireless internet access. These factors form a more premium experience and command a higher price point. On the other hand, Dunkin' Donuts has more competitive pricing, focusing on the middle class and take-outs. It intends to be the lowest cost provider in the market while maintaining quality above an acceptable minimum.

Now Dunkin' wants to get more strength in providing a comfortable and social environment for premium-price paying customers. Dunkin' wants to downsize part of its franchised, low service locations, and create more well-designed coffee houses for comfortable seating and social activities.
