If you are visiting Austin or passing through on I35 toward Dallas, and want a treat, they have what can certainly be called world famous donuts.
It has been "the favorite" donuts in Austin area for as long as I have been here (25 years).
There is a never ending line of cars driving through most mornings picking up orders.
Still wait is usually only 5-10 minutes--they are very efficient.
It is a unique taste that is really great. Pretty much makes me not want to ever eat any other donut. They also have ciniman rolls etc, but its the donuts that are over the wall.
