Before taking the stage for a private show inside the Cosmopolitan Hotel in Las Vegas with his band Bush, Gavin Rossdale
stopped in for a bite at STK with his bandmates. The guys shared beef and tuna tartare, seafood platters, king crab and Dover sole. For his entrée, Rossdale ordered a Wagyu beef filet, which he enjoyed with a knife emblazoned with five carats of diamonds.
