Brains, the Cardiff-based brewer and pub operator, has opened a second site under its Trees all-day café bar concept in the city and is looking at the possibility of opening further units under the format. The Pear Tree has opened in the Roath area of the city and follows the successful launch of the first site under the concept, the Lime Tree, in Newport in 2009. The Trees concept is the group’s more laidback and quirky take on the all-day café bar format. The company, which launched its first restaurant site, Greenwood & Brown in Cardiff before Christmas, carried out an £8m capital investment programme in 2011.
