Single O feels rooted in Reservoir Street. The Surry Hills room is long and narrow, with the main counter running through the middle, tables spilling onto the pavement, and Sideshow next door handling much of the takeaway traffic. A few blocks south of Central, it lands as both a neighbourhood regular and a Sydney reference point, which is why it still belongs on the shortlist.
Coffee
This is where Reservoir blend makes the most sense, backed by rotating single origins and a brew-bar setup that gives filter coffee real space in the visit. Sideshow keeps batch brew, pour-over, cold brew, and espresso specials moving without clogging the cafe, so Single O can serve commuters, coffee people, and sit-down breakfast tables at the same time. That flexibility is the clearest reason to come here instead of one of the many newer Sydney cafes built around a narrower offer.
Food & Pace
Food is a major part of the stop, not an excuse to linger. The menu usually runs to a full breakfast and lunch slate rather than a token pastry case, and details like banana bread with espresso butter keep the house style from feeling generic. The tradeoff is noise and turnover: this corner gets busy, outdoor seats go fast, and the room is better for a meal and one or two cups than for a long, quiet camp-out.
What people go for
People come for Reservoir blend, Sideshow's filter options, and a breakfast that holds up even if coffee is the main reason for the trip. That mix matters in Surry Hills, where there are plenty of cafes but not many that still feel this central to the city's everyday coffee rhythm.
Why Filter Notes has shortlisted Single O
Filter Notes has shortlisted Single O because it still does more than one thing well without turning into an all-purpose cafe. The original room, the house coffee, and the brew bar next door give it a shape few Sydney shops can match, and the food is strong enough to make the detour worthwhile even when the line is moving fast.
