Two well-loved names on London's top dining scene are joining forces for a short sandwich drop this March. Atis and The Dusty Knuckle are collaborating on a limited-edition focaccia sandwich, marking the first time Atis has properly stepped outside its salad comfort zone.
Launching on 2 March, the Atis x Dusty Knuckle Buffalo Caesar Focaccia will be available for just two weeks, with only 25 sandwiches made per day at each Atis location. It's a first-come, first-served situation – once they sell out, that's it for the day.
The sandwich pays homage to Atis' best-selling Seiz'a Caesar salad, made with Dusty Knuckle's focaccia which forms the base, stacked with romaine lettuce, avocado, blackened chicken, parmesan, crispy shallots and Caesar dressing, finished with a hit of buffalo sauce. It's a collaboration that leans into both brands' reputations for flavours and careful sourcing.
There's a practical side to the partnership, too – Dusty Knuckle's bread isn't always easy to find in central London, and this drop effectively brings the bakery's focaccia into neighbourhoods across the city via atis' 16 sites. For Atis, it also signals a wider menu shift; from March onwards, slow-cooked soup and Dusty Knuckle focaccia will join the permanent offering, suggesting the brand is expanding beyond its salad identity.
Alongside the limited sandwich, atis will introduce a roast tomato and pepper soup designed to be paired with focaccia, either as a combo or as an add-on to the existing menu. It's a small but notable evolution for a business that has largely been defined by its healthy bowls.
According to Atis co-founder Eleanor Warder, the collaboration marks “a new chapter” for the company and reflects a long-standing admiration for Dusty Knuckle's baking. Dusty Knuckle's managing director, Max Tobias, describes the drop as a chance to go big on flavour and bring something new to London diners, albeit briefly.
