From Hornstull T on Långholmsgatan, walk up Hornsgatan 100m to the On-Inn on your left.
Or from Hornstull T on Hornsbruksgatan (by the park), walk 20m along Lignagatan and turn left.
Note, this is a new Lion Bar (cheap) - it used to be a Bishops Arms (expensive).
Order and pay for food before the run for a cheaper price.
