In my humble opinion that would be a Brioche bun. Please dispute that if you have a better idea. I find that most high end restaurants serve Brioche buns with hamburgers and pulled pork sandwiches. Most restaurants use a plain white bread hamburger bun like you buy at Safeway. This bun needs to be really special. It can't over power the hamburger patty that is intended to be the star of the dish.
