Week No. 10 Duff's Tavern on Main
If you think the most important part of a burger is the burger, then Duff's Tavern on Main in Vermillion is where you want to be.
The restaurant has three burgers -- the hamburger, the cheeseburger and a California burger. There are no weird toppings. No sauces. No frills.
What there is, though, makes up for what there isn't.
