You're honestly paying a premium for the environment at hard rock, but that's not to say this burger ain't good.
Premium beef patties and a mix of provolone cheese and caramelized onions just makes this the only burger I that doesn't need sauce (we'll except for Hard Rocks smoky burger sauce)
Is it worth RM78? I'd say it's probably close but I wouldn't be willing to fork out that much, at most I'd give them RM50.
