It was the first time we'd eaten a meal at the restaurant - previously we'd only been there for snacks and drinks (very good snacks and drinks they were, though!).
Our food was absolutely excellent (French onion soup, filled chicken breasts on a bed of mushrooms, and malva pudding with koeksuster/Amarula ice cream were a few of the options on our set menu), and the service was great. The waiters were incredibly polite and very efficient, and the portions of food were impressively generous.
If you're a fan of value for money, then don't miss their winter specials - R99 for a 2-course meal or R125 for a 3-course meal, both including a glass of wine. If you're looking for a cosy but stylish spot for dinner, I can definitely recommend Sinn's.
I'm sure it will amuse you to know that when we were leaving Kerry-Anne and I spent five minutes trying to work out why on earth the pay-on-foot parking machine wouldn't take our parking ticket, till we realised simultaneously that I was, in fact, trying to put the parking ticket into the automatic teller machine, conveniently located next to the pay-on-foot machine. And I can't even blame the whisky - its effects had long since worn off. :D
