Illegal Burger

Opened in 2010 with the hopes of serving Oslo’s best burger, this fast-casual spot has had much success and now has several locations. The most convenient location for visitors is the outpost set on the main street in Grünerløkka, which features retro, cafeteria-style booth seating and an open kitchen. The lengthy menu boasts many varieties of burgers (all of which can be made with veggie, fish or beef patties) with statement-making names like the Hot Mama Deluxe, which comes topped with bacon, cheddar, BBQ sauce, guacamole and jalapenos. And while it is not on the menu, the foie gras burger is worth asking for.
