Stop Valve Café & Bar:
This tiny cafe sits beneath a multilevel carpark opposite the well known Watters Gallery and beside a huge mural by street artist Heesco. The image is based on the imaginative work of Shaun Tan, best known for his childrens picture books and in particular one entitled The Lost Thing.
Excellent coffee and the cafe staff are suitably gracious and helpful.
