Its not cheap for a little cup. But the flavours are just so unique. It is worth a try.
They have there loyalty program as well. That keeps me going back to them. I love it.

Approximate cost: $4

I've been to Gelatissimo in Burwood around 5-6 times. Their ice cream is absolutely amazing but one thing I really hate is that if you get there half an hour to an hour before closing time, you only get some flavours, not all. Reason being "All other flavours are prepared for tomorrow." So, get there early! =p
