I've been to over a dozen Hard Rock Cafes, so there was no question I'd be stopping at their Pittsburgh location on my recent visit for a Pirates' game & stop at the must-see Warhol Museum.
I went during mid afternoon (3:30 or so) & was politely greeted & seated right away. Visiting a Hard Rock, I generally order the same thing every time on my first visit & they nailed it - the Honey Mustard Grilled Chicken.
Some fun mementos from rock & roll history, of course - boots owned by The Edge, a Pittsburgh Steelers' themed guitar, Eddie Van Valen's guitar from a show in the city & tons more.
The service was fast, friendly & efficient & a visit to the Rock Shop after my meal did do a bit of damage to my wallet. If I return to Pittsburgh, I'll definitely be back.
