Called Really Happy Chicken, the restaurant will feature a plant-based menu of Southern American-style fast food staples.
The core of the offering will be a range of seitan 'chicken' burgers, fried in a seasoned batter and topped with lettuce and vegan mayonnaise.
There will also be a selection of sides available, including fires; as well as vegan buffalo chicken wings.
The concept is similar to London-based brand Temple of Seitan, which operates sites in Camden and Hackney.
Really Happy Chicken claims to be Brighton's first vegan fried chicken brand, and says it is 'on a mission to making vegan and sustainable living more accessible to the masses for the good of the planet and all it’s beings'.
In June, Youtube personality Mikey Pearce is to launched his own vegan burger concept in the city called Clean Kitchen Club, which has aspirations of becoming the 'fastest growing plant-based delivery-kitchen brand in the UK'.
Meanwhile, vegan pizza brand Purezza is to open its second south coast restaurant next month, having taken over the former Patisserie Valerie site near Palmeira Square in Hove; as well as launch its first site in Bristol.
