Rosslyn is an independent group of ten coffee shops concentrated in the City of London. Founded in 2018 by Australian Mat Russell and Irishman James Hennebry, it combines the close attention of an Australian cafe with the warmth of an Irish pub. Across the group, the focus is high-volume specialty coffee served quickly and with care, with separate coffees chosen for milk drinks, black coffee, and filter.
This review uses the original shop at 78 Queen Victoria Street as the anchor for that wider London recommendation. We call it out because it is where Rosslyn began, it opens on Saturdays, and its small, bright room shows the brand's fast but friendly service at its clearest. The compact counter, pastry line, window seats, outside bench, and steady queue are built for the Square Mile, London's central business district, rather than a long cafe stay.
Coffee
Most people come for milk drinks, and Rosslyn has earned its reputation there. Flat whites and cappuccinos stay precise even when the room is full, while batch brew gives you a quick black-coffee option. Queen Victoria Street also runs an Off Menu programme of rare coffees from international roasters, kept in individual frozen doses and brewed to order. That extra filter range is a specific reason to choose the original shop when you have time to look beyond the usual order.
Food
Food stays in support. There are pastries and the orange cake has its own following, but Rosslyn is not trying to become a breakfast café. That restraint suits the place. The room is strongest when the coffee is the reason you came and the pastry is there to keep pace with it.
What people go for
The feel
The shop is better for a short stop than a long stay. Seating is limited, the surrounding streets are office-heavy, and the whole operation is tuned to repeat weekday use. That is exactly why it works. Rosslyn gives the City a coffee bar with real hospitality instead of pure transaction, but it never forgets the pace of the neighbourhood around it.
Why Filter Notes has shortlisted Rosslyn Coffee
Filter Notes recommends Rosslyn as a London coffee group because it handles very high-volume service without losing precision or warmth. Queen Victoria Street is the location to start with: the original room makes the brand's approach easy to see, offers the deeper Off Menu filter selection, and is one of the Rosslyn shops open on Saturday. Come for a flat white at City speed or make time for a rarer filter coffee; choose somewhere larger if you want to settle in for the afternoon.
