The new design will serve as a template for all future openings, said CEO Dave Prokupek, who has plans to open 60 to 70 units this year.

The updated décor features softer lighting, earthy materials and brighter colors that offer a more contemporary feel.

Although the decor of each restaurant will be similar in some areas, they will still be a bit different. The chain will continue with its tradition of developing a local burger that incorporates the favorite ingredients and taste profiles of each region.

Some of the guiding principles leading the new design make it simple, natural, comfortable, but modern and relevant for all occasions, said Tom Ryan, founder of Smashburger.

Some of the enhancements to the interior design include softer lighting, high-tech digital menu boards, exposed wood plank ceiling rafters, stainless steel table trims, localized graphics and art.
