The brand is only available through Deliveroo, and operates from four kitchens in Peckham, Blackwall, Islington and Battersea, according to BigHospitality’s sister publication MCA.
It serves katsu, made with either cauliflower or curry-marinated chicken, served with either rice, avocado salad or roti.
Side dishes include carrot and cabbage sesame slaw; sweet potato fries; Asian broccoli in soy and garlic dressing; and sticky hot wings.
Busaba is not the first group to use Deliveroo to launch a spin-off brand. Sushi hand roll restaurant Yoobi launched Lolo Poke through the takeaway delivery company; and Thai group Chilli Banana now operates three brands that are only available through Deliveroo.
October of last year saw Italy-based pizza restaurant Lievita use the delivery-only platform to expand to the UK.
Deliveroo Editions launched in April 2017 to allow the company to serve areas that are under-served by traditional eat-in restaurants.
The launch followed a trial of the concept, known as Roobox, which launched in Camberwell, Battersea, Dulwich and Canary Wharf in 2016.
At the time of the launch, the company was working with established brands such as Meatliquor; Busaba Eathai; Franco Manca; Crust Bros; and Moto Indian Kitchen.
