The answer to 19a provoked a load groan, thank you for that Malone. Still can't get a handle on the main course or 8a. I cannot think of anything remotely 'posh' about SR's or what else they could be, I keep thinking of the Berni Inn menus of the 70's to try and get an idea, but it was all steaks and either plaice or scampi depending on how 'posh' each particular Berni was. I think I must have some of the wrong letters in the RH perimeter but can't currently see where I am wrong.
