Next month, the group will launch a 20-cover restaurant on Fonthill Road in Finsbury Park. This will be followed in December by a 30-cover site on Caledonian Road, near King's Cross.
Deacon Rose, who founded Coqfighter in 2014 with friends Troy Sawyer and Tristan Clough, tells BigHospitality both sites will serve a full dine-in menu that includes its 'original' burger with a fried chicken thigh, shredded iceberg, pickled red onion, sambal mayonnaise and Korean hot sauce; 'K wings' cooked in a sesame batter and served with soy garlic glaze and Korean hot sauce; and dashi and smoked paprika fries.
A range of beers, wines and cocktails will also be available.
Looking ahead to 2022, Rose has confirmed that Coqfighter will open a new Deliveroo Editions kitchen in January in Maida Vale. It is also planning a further four bricks and mortar sites in the capital, as well as regional openings.
Coqfighter has proactively sought to both maintain and expand operations throughout the pandemic.
Prior to the first national lockdown it operated two Boxpark sites in Croydon and Shoreditch, as well as a full-service restaurant on Beak Street in Soho.
In June last year it opened its second permanent site, described as a 'neighbourhood takeaway shop', in Brockley.
It has also trialled and established various dark kitchen locations in the capital, with sites currently in Crouch Hill, Leyton and Balham. Last month it also launched a new regional kitchen in Bristol.
Coqfighter also operates a vegan fast food sister concept, Mercy Burger, in Boxpark Shoreditch, which launched last summer.
