Co-founders Yasmine Larizadeh and Shirin Kouros, told BigHospitality in June they had planned to open a third site in London this year, but had not yet secured a location.
The 35-cover Good Life Eatery Motcomb Street will open in February with plans to serve The Good Life's signature 'energy-boosting breakfasts and lunches, guilt-free snacks, shakes, juices and desserts' under its existing 'formula'.
"It's been a tough ride, but we are thrilled to be expanding The Good Life family and opening our third site," said Larizadeh and Kouros.
"Our Marylebone cafe has been so well-received thanks to the local community and current fans and we cannot wait to bring a clean, fresh dose of The Good Life to such a beautiful pocket of London that's experiencing a bit of a renaissance."
The Motcomb Street branch will have a sleeker look than its original sites in Chelsea and Marylebone while maintaining the brand's 'casual, laid-back approach' they said.
The menu will include a mix of Good Life classics, such as winter-warming bowls, lean machine bowls (ratatouille, meatballs or falafel served over quinoa or caulirice) and superfood salads.
