Caffe Di Vita is my favourite cafe. It is a little place in Wilston at 1 Macgregor St (Cnr Kedron Brook Rd) that does an awesome sandwich with great service and nice coffee. I almost always order the same thing, and it is the chicken and avocado sandwich with a side of chips and extra bacon added. My girlfriend and I have been going there for ages thanks to the service. Being recognised as a regular by the owners is definitly a factor too.

They use Segafredo beans and do a decent coffee. It is not the best coffee I have ever had, but the quality is consitant, and the service and food make it a place to go.
