The name - which is Slovene for 'grove' and pronounced 'guy' - is a slightly exaggerated reference to the modest row of trees shading the large outdoor seating area. Inside, a small ground-level bar with stained-glass windows, brass railing and dark green everything else, does a commendable job of concealing the colourfully funky lounge downstairs, which is popular with students from the university across the street. If you fancy striking up a conversation, a good icebreaker could be the bar's past reputation as a hangout for some of the city's more nefarious characters.
