Ca Phe VN, the specialist Vietnamese café operator, is believed to be close to securing a second site in London, only three months after opening its first in Islington. The concept, which was founded by husband-and-wife team Rob Atthill and Tuyen Hong, is understood to be close to acquiring a site in Clerkenwell. Before opeing in Islington, Ca Phe VN had previously operated as a 60-cover street café at Broadway Market every Saturday.
