They opened a DD in Walnut Creek, about 5-10 miles from me. Took my son there awhile back, left without buying anything. They wanted $1.75 per donut and they weren't much bigger than a silver dollar.
I'll stick to my mom & pop donut shop which is appropriately named "The best little donut house in town". It's owned by a Laotian or Vietnamese couple. Great people, always give me extra donut holes or donuts.
They make a ham & cheese croissant that is not only HUMONGOUS, but tasty. It overlaps a 10" paper plate they serve it on.
