I have tried many of the Froyo shops across not only Sydney but also recently in the USA. This is by far the best quality, some others taste too sweet and too much like ice cream (I doubt that they have any yoghurt content at all), and others are way too Icey. Delite has the perfect combination, it is nice and creamy, yet full of flavour and just the right combination of tartness and sweetness.
The service was quick, very friendly staff, and an awesome music selection which is very hip.

Approximate cost: $4
