Illegal Burger

Illegal Burger is an Oslo cult favorite, repeatedly named among the city's best burgers, prized for smoky Josper charcoal-grilled patties on a deliberately crisp, non-brioche bun and crispy salted potatoes with aioli. The Gourmet (truffle mayo, mushrooms, brie) and Hot Mama are the most-recommended picks, and most reviewers call it good value for Oslo. The main caveats are the tiny, often-packed original Møllergata location with limited seating and occasional waits.
