The ‘Bunker’ is a wonderful cafe with a positively enormous glassed-in terrace tacked onto the Bunkier Sztuki (Art Bunker), a cutting-edge gallery northwest of the Rynek. The garden space is heated in winter and seems to always have a buzz. Excellent coffee, non-filtered beers, and homemade lemonades, as well as light bites like burgers and salads. Enter from the Planty.
