If you decide to go to Gothenburg, do not miss the lentil soup, Faki at Alexandras Soppkök in Saluhallen, Kungstorget. (Tramstation Kungsportsplatsen)
At only 30 SEK it is a culinary miracle! Red hot and tasty.
Alexandras has daughter-shops in Malmö and Lund as well. The one in Malmö ( Saluhallen by Lilla torg) is excellent as well, Lund I have not tried.
Wanna make your own faki? Try this recipe. Or this one. The secret is in the red vinegar.
