La Tasca has announced plans to roll out its "Bar de Sangria" concept across the majority of its estate during August.
The sangria bars will feature a selection of 15 different sangrias from the Favoritos and Clasico menu sections.
The move follows a successful trial of the format in La Tasca's Leeds site, which paved the way for its introduction in a total of 35 venues.
Commenting on the move, chief executive Simon Wilkinson said: "After a successful trial we are launching our Bar de Sangria concept into the majority of the La Tasca estate alongside our Bodegas Wine Bars & Cava Bars.
"Trade is very buoyant with our new La Tasca & Rioja Bar in Leadenhall trading ahead of expectations for this time of year, we are at legals on a new shell site at the refurbished NIA in Birmingham and hope to announce a further major acquisition shortly.
"Next month we will launch a radical new improved menu in La Tasca the first major change since we switched from 85% frozen food to fresh food in October 2012. Our La Vina & Bellota sites successfully launched a new menu last week which has had amazing guest feedback."
