Probably the best bar on Plac Nowy, ”Colors” is a French-style cafe with an imposing zinc bar, banquettes, and other pleasing touches of Francophilia—old theater posters, Serge Gainsbourg paraphernalia, and a huge bottle of Pernod behind the bar. By day, regulars enjoy breakfast and check their e-mails. By the evening, beers flow and the chat gets loud.
