Dugg Burger is expected to open in late December at 4701 W. Park Blvd., Ste. 110. At Dugg Burger, guests pay first and then select from 12 classic toppings. The restaurant reverses the burger-building process by digging out the top portion of the bun for customers to customize his or her burger. Dugg Burger also offers french fries, desserts and a selection of craft beers. www.duggburger.com
