There's plenty of choice in Donvale!
I live near Ciao Man at Lucky Corner - Springvale and Mitcham Rd intersection - opens at 6am daily!
At Tunstall Square:
Espresso Lane - Coles side of the Square
Cafe Cube - Donvale Flower Gallery side & tucked in the corner
L'Affogato next the Newsagent has been a stayer for a long time.
The Black Stag is the latest to join in, on corner of the carpark and Tunstall Rd.
I go them all regularly and they're all great and lovely owners and staff.
I live in-between Mitcham/Donvale and always find the best cafes are in Mitcham.
Try Dark House and Misho's cafe.
