This is a real Stockholm institution!
A humble little food cart on Södermalmstorg (by Slussen) is the perfect place for a light meal or a filling snack.
They offer fried herring, fried herring and more fried herring! You can get it served on top off different kinds of bread (knäckebröd being the most traditional one) and with your choice of condiments! It will take a minute while the fish gets fried to order, but is a quick and easy eat at a beautiful location!
