Although open early for breakfast, the real virtue of Koko is revealed after midnight when you want a civilised sit down meal without the company of tzatziki dribbling drunks. Serving generous portions of stodgy Polish classics like pierogi and fried cutlets for the same price as a kebab deep into drinking hours, this is a handy alternative for anyone looking to fortify their stomach without making a mess of their shirtfront. Formerly stuffed into an obscure Old Town back corner, Koko has expanded into a second street-side dining room which significantly outclasses the original space in terms of rustic charm.
