Telephone number is +46 08-16 03 50. Location is about two blocks from the "Radmansgatan" subway stop, which is two stops from the Central train and subway station, called T-Centralen. Anything near the train is easily reached from most of Stockholm.
This Hard Rock Cafe is comfortable and cozy compared to other Hard Rock Cafes. The bar is off to one side when you enter. You can't miss it. It has a black Cadillac convertible suspended over the round bar.
There is a gift shop near the front door opposite the bar for the popular (at least with my family) logo souvenirs.
Of course, they have many collectable rock music instruments, gold records, outfits or articles of clothing, and play recorded rock music at all times. This location has a lot of music instrument amplifiers hanging on the walls. There were so many that they couldn't be for function.
I sat at the bar and admired their small shrine for The Who, with autographed pictures that were perfectly matted and framed.
I think the menus are universal (American food) at all Hard Rock locations, so the draw is the rock memorabilia, and the amusing decor, often supplemented with motor vehicles.
