Burgerville (originally Burgerville USA) is a privately held American restaurant chain in Oregon and southwest Washington, owned by The Holland Inc. As the chain's name suggests, Burgerville's sandwich menu consists mostly of hamburgers, though it also offers chicken and turkey sandwiches, vegetarian burgers, and halibut fish and chips. All Burgerville locations are within an 80-mile (129-km) radius, mostly in the Portland metropolitan area. The chain had annual revenue of around $75 million in 2010, at which time it had 39 locations and about 1,500 employees.
The chain's most significant differentiation is in its use of local ingredients and natural ingredients, such as Tillamook Cheddar in its burgers, and locally grown strawberries in its milkshakes and sundaes. Throughout the year it offers seasonal items such as milkshakes made with hazelnuts, fresh pumpkins, fresh raspberries, fresh strawberries, and blackberries, and side orders such as Walla Walla onion rings, sweet potato fries, tempura-style fried asparagus and Yukon Gold potatoes.
