Flamme Burger Grünerløkka

Flamme Burger keeps things focused: juicy, straightforward burgers built around good buns, well-chosen sauces, and no fussy extras. The classic cheeseburger is a standout, with crispy chicken, veggie, and truffle options for variety; it’s more of a casual burger stop than a destination for lingering, and the fries can be hit-or-miss.
