207-215 Victoria Sq, Adelaide SA 5000
It seems this place became an institution overnight. And it's not without reason. Food is interesting, vast, and generously served. The coffee is good too, but the food is the highlight. Pop in, grab some lunch, and then head onto a quieter coffice for the rest of the day.
There's AdelaideFree/Internode Hotspot WiFi and a meeting room that can be hired out that has powerpoints. If you’re meeting a client, sit out the front if the weather is good - it can get pretty noisy inside.
