Named after the two adored canines she shares with her husband Stephen, combined with the first names of the couple's favourite screen idols, Sidney Poitier and Audrey Hepburn, this cafe epitomises vintage, 1950s charm.
Once an old paper factory and then a Polish butcher, the site for the cafe is quite unlikely for the busy end of Fitzgerald Street, but this, Ms Hanrahan says, is just the way she likes it.
"It's very much a destination place, so people will specifically come here for our triple-choc brownies or just relax in the lounge chairs to read and drink coffee," she says. Those brownies are a deadly combination of milk, dark and white chocolate and copious amounts of butter.
All the cakes, loaves, slices and goodies are made daily by Ms Hanrahan (a Delia Smith and Maggie Beer devotee).
"I wanted the space to feel like a lounge room, so if I've been baking (the small oven is behind the service counter), people can smell the aroma of home cooking as they enter," she says. "We also book the entire space on Sundays for afternoon and kitchen teas or baby showers. It's from $25 per head and I bake everything on the day so food is warm when guests arrive."
Ms Hanrahan uses organic products where she can for her treats. Her sister Jacinta makes a mean chai latte using organic Rubra tea.
Among the vintage chairs and sofas (all for sale), are local and Australian giftware, wallpapers and prints, making the cafe a perfect venue for her Sunday afternoon sewing classes.
