The really great thing about the Rio Bar is definitely its cosy outdoor area. The tables on the little square next to the Sihl river (the smaller of Zurich's two rivers) are the perfect place for a coffee after shopping or an early evening beer (Zurich's Turbinenbräu on tap). Indoor it's tiny but definitely en vogue with the dark wooden bar. For lunch there is a menu which changes daily and in the evening there are antipasti and sandwiches for snacks.
