As much as we dislike the word 'classy', this really is the most appropriate word for this café that adjoins the National Theatre. Housed behind the only modern façade on Slomoška Trg, it does its best to pull off an old-school piano bar vibe, and with its high-back red booths, dark wood chairs and depth-adding mirrors - all it's really missing is the requisite cigarette and cigar smoke haze.
