Galoshnik Restaurant..anyone remember?

I've been trying for ages to track down a sketch about a Galoshnik Restaurant which I remember vividly. In it RB was a disgruntled Eastern European waiter to RC's customer with posh girlfriend. It involved their going through the menu making remarks and him writing it all down as an order and commenting, e.g.
"It's disgusting!"..."Dix gustings? That's a lorra gustings!", and also when the woman asked for "The smallest room", he writes "One smaal-eshtroom". The 'visual punchline' at the end involved RB coming out of the kitchen with a trolley laden with dishes, including 10 plates of food each with a whole banana stuck vertically in it (the 'dix gustings'). Do YOU remember it? It isn't in ‘All I Ever Wrote', nor does an internet search bring it up. I'd love to see it again, or even just read it.
CAN ANYONE HELP???
