Jettz Burger

The Spis take

A branch of the Jettz Burger smash-burger chain (Oslo plus a handful of other Norwegian towns), doing thin-patty smashburgers from fresh Norwegian beef at Majorstuen. It's a competent, delivery-friendly fast-casual option rather than a standout, with decent app ratings and meal deals aimed at the takeaway crowd. Fine if you're nearby and craving a smashburger; the format is familiar rather than special.
