Sostrene Karlsen

About

Søstrene Karlsen, located on Trondheim’s vibrant Solsiden street, invites diners to experience a blend of Norwegian culinary tradition and contemporary flavors. Renowned for its signature blåskjell (blue mussels) and the city’s finest fish soup, the restaurant offers a menu that showcases fresh, locally sourced seafood alongside thoughtfully crafted vegetarian and vegan options. The atmosphere is relaxed yet sophisticated, with a spacious indoor setting that feels like a rustic home and an inviting outdoor terrace that’s perfect for al fresco dining in the spring and summer months. Guests can enjoy everything from a quick lunch to an extended dinner, with the option to book the charming “Chambre Séparée” for intimate gatherings or the terrace for larger parties. Ca. one hour is enough to savor the seasonal tasting menu, but many return for multiple courses or to take advantage of the lively “After Works” evenings, featuring a rotating buffet and live television of local football matches.
