I vote for the Rusty Duck in Dexter
That's the place I was trying to remember that I saw on Iowa Public Television:
My main stop in Dexter is at the Rusty Duck to sample the winner of the Iowa's Best Burger Award. Over 200 restaurants vied for the honor but Brad Waldron's Rusty Duck established in 2004 took the prize for one impressive looking burger.
Waldron: The particular burger that won it this year was the bacon cheeseburger. We grind our own meat. We use top sirloin ribeye trimmings for my steaks and we grind it ourselves, patty it. There is really nothing that we do any different. It is just that you know it is the same burger I have been serving for years. After we make the cheeseburger we put about 10/12 pieces of bacon on it and it is stacked pretty good. You know it is definitely a dinner. If you can't eat it you can definitely take it home and eat it the next day.
Kaercher: 10 to 12 pieces of bacon? I mean wouldn't two be enough?
Waldron: No, two wouldn't be enough.
Kaercher: And I think it is pretty safe to say that no one walks out the door hungry.
Waldron: We have pretty good sized portions on everything. Like our hamburgers are 14 ounce, pork tenderloin is 10/12 ounces. We go through quite a few to-go boxes.
