The restaurateurs behind the Chelsea Quarter Café have partnered with London design and furniture store Heal's replacing Peyton & Byrne, which left to pursue a new growth strategy.
Doron and Valeria Zilkha opened two operations at the Tottenham Court Road store last week.
A ground floor mini-kiosk, launched as Heal's Quarter Café Express, offers takeaway pastries, sandwiches, salads and coffees, along with adjacent seating for up to 20, both on the pavement and immediately by the café.
"Heal's is an ideal partner for The Quarter - the combination of a phenomenal retail and style heritage but with a contemporary edge is what appeals to us," commented Doron Zilkha.
"The Heal's customer is our customer - and we are looking forward to providing them with a new all-day offering, to have its own destination identity and also to enhance their regular shopping experience."
A spokesperson for Peyton & Byrne said the company has come to the end of its commercial agreement with Heal's, adding: "We have recently been awarded a multi-million pound investment to support Peyton and Byrne on the high-street and continuing as an in store operator did not fit with this strategy.
"It has been a pleasure working with the Heal's team and hope their new venture is successful."
The Quarter Group launched in 2006 and currently owns and operates Chelsea Quarter Café on King's Road, and the River Quarter Kitchen in Plantation Wharf, Battersea, facing the Thames.
A further site - to be called Royal Quarter Café - near Buckingham Place, in Wellington House, Buckingham Gate, is expected to open in late spring 2013, and the company said it has ambitious plans to expand with further London sites in the next two years.
