keep in mind though that restrictions on visits are still largely dependent on carrier and route... i myself was lucky enough to get a full 737 visit from push-back to shut-down between PLZ and JNB in SA just last month... Full dinner service in the jumpseat too, including hot coffee and normal (i.e. metal) cutlery... and, yes, i'm just PPL (though had been in PLZ for a renewal and some extra training, which no doubt helped my case with the captain...)
good luck!
