The Spis take

The Oslo (Storo) outpost of the American retro-diner chain, doing burgers, fries and thick milkshakes in a jukebox-and-chrome package. It's a competent, familiar comfort-food stop that kids and homesick Americans tend to like, though prices run high for what's essentially chain fast food and locals will point you to Oslo's better independent burger joints. Fine for a fun, no-surprises meal; not a reason to cross town.
