While I'm visiting my mum in Haberfield I would stop in to the Galleria almost every morning after my run. After the third time, the staff knew my order before I said it. :)
But what is really good is the coffee - excellent flat white. And the toasted banana bread with butter - divine. They also make wraps, sandwiches and paninis but my favorite time was breakfast. There is a small amount of seating inside and also on the sidewalk outside.
