Although I did not detect a major quality difference, my wife claims that King Donuts on State Street and 17th is better than Dunkin' Donuts on Commercial. I will note that it was very clean inside. The kitchen is exposed from the service counter and I could see that their operation was clutter free and efficient. The donuts at King's are average. By saying it's average is actually a compliment because an average donut is still a lot better than no donut. A glazed twist hit the spot with my home brewed coffee on my way across town on this morning. The dining room was busy but there was no wait to order to go. Even with the crowd, there was plenty of donuts of every variety to choose from and the cashier was friendly. If you are hungry in the morning and find yourself east of the capitol building, don't be afraid to try King Donuts.
