This area contains a lot of the busy central area including the central station (T-Centralen) and a lot of the big stores.
Though I haven't been here yet, I'm sure it belongs here because they are connected to another cafe in another city that I do know...
The best ice cream in town. Has another location at Hornstull on the west of Södermalm
Their hotel bar is pretty neat and a good place for a drink super close to T-Centralen.
