I know Krispy Kreme's going to have a lot of favorites, but for me I like Daylight Donuts.
Up here in Tulsa, I go to the one on 91st and Sheridan. A guy named Paulie owns it. Super nice guy. I've been to one on Memorial and 106th, but they didn't seem too nice.
Also, the one on 15th and Harvard is great. Mary always throws in an extra donut or two for us.
I'm not going to make this a poll (because I don't know how).
