Busi is a lot. Busi is purple and turquoise and dayglo and lurid. Busi is Instagram. Busi is flowers. Busi is two-tone rose lattes and bubble teas. Busi is ... Serving one of the most exciting coffee menus in the city. It’s a trip, and with Copenhagen’s April — rarely, if never seen in London — anchoring the coffees alongside a filter menu with three geshas from Ninety Plus, renowned for its rare, expressive roasts, a genuinely boutique edition to London’s scene. And it actually delivers on its promise.

A dinky space defined by a huge, striking, wraparound mural from Gabe Sapienza, Saint Nine Coffee has made a strong start to life in Southwark with coffees from Assembly and Roundhill currently propping up the bar. The offering is admirably minimalist — no food in sight bar some cookies — and that focus comes out in the drinks.

Beginning life as a pop-up at Sharps — a barber in Fitzrovia that is also an unlikely incubator for many of the London coffee scene’s talents — Good as Gold has now taken root in Brockley with a rotating cast of roasters. London mainstay Caravan is often the anchor, with filters coming from the likes of Amsterdam’s Fried Hats — identifiable by their pop art glass jar packaging — and Obadiah, from Edinburgh, and up-and-coming London roaster specialising in microlots, Plot.

Edison Shehu’s debut cafe in Battersea is a quick spin through Battersea Park from fellow neighbourhood hit Kapihan, and his approach to coffee is aptly focussed on rotation. Currently, Kiss the Hippo and Oxford’s Ue are in the hoppers, while very online coffee fans will be pleased to find “Monsieur Claude” — an Ethiopian coffee named for Roundhill Roastery’s Oli Bradshaw’s cat — on filter.

The latest addition to this burgeoning coffee-as-lifestyle-brand packs some serious gear for the espresso heads — a Slayer machine for fine-tuning shots and something called an Ubermilk that steams of its own accord — into a space that, definitely pre-pandemic and increasingly as the world emerges, would otherwise be given over to high-volume homogeneity.

A social enterprise training people who face barriers to employment in speciality coffee, this space at UCL’s architecture building is Well Grounded’s first permanent cafe operation. With five filter coffee methods on offer, quality beans from Caravan, and batch brew starting at £1.30 a cup, it’s a cafe that focusses on excellence while firmly in tune with the ethos that brought it to life.
