I met with an old friend for lunch at ‘21’ Knox St this week. I’d not been there before but will sure return. It is a smallish café/restaurant in the heart of Double Bay and obviously frequented by a lot of European style patrons in this very upmarket area. It has a history having been opened some 50 years ago. The staff were very welcoming, despite having no booking, and most attentive. Service was prompt and efficient. For lunch it was superb – the oysters natural were the best Sydney Rock Oysters I have enjoyed for a while – they were exceptional. The crumbed lambs brains well presented and the desert of chocolate mousse – to die for. Worth coming back for that alone. A great lunch, a fantastic venue, and superb selection of food on the menu.
