Gunnarssons is a specialty bakery in the midst of Södermalm on Götgatan.
Their speciality is their freshly baked bretzel. The bretzels (chewy, salty pretzels that succeed at being both crispy yet soft at the same time) are only sold on Fridays to guarantee freshness. Buy some of their home-made, mouthwatering parmesan cookies too. Or their special chocolate almond pastry which is an homage to Greta Garbo (who lived close by, and actually worked at a hair salon housed next door, back in the 1920's). They're called Garbo's Tears and they are amazing.
