We had a Krispy Kreme in my area but it went out of business; I have yet to try one of their doughnuts. According to the Krispy Kreme
website the closest Krispy Kreme is 163 miles away in Austin.
When I was a kid we would always stop at Dunkin’ Doughnuts on our way to Wisconsin. I have never understood the appeal. I only know of one Dunkin’ Doughnuts in all of Houston but I’ve never been.
So I voted "Other" and I'd also like to cast my vote for Fatback.
In Houston I would say it is Shipley’s Do-Nuts that reign supreme (86 locations). Their pretty much the go to place for doughnuts. I have one right down the block from my house and after I make it home from a late night I can smell them cooking doughnuts from my driveway. I hardly ever eat doughnuts but on the rare occasion that I do it’s Shipley’s
When it comes to breakfast food it's all about Klobasneks aka Kolaches.
/edit: Oh yeah if you are ever in the Clear Lake area
Morning Kolaches is the place to go.
