Sage
Is a place you don't want to miss. it is in the old "mihai eminescu library" building and it has lots of tea sortiments from all over the world. there's also newspapers and books you can read, a piano and social games that you can borrow for free. the personnel also speaks english and, when the owner is in, people have been known to get freebies. very nice atmosphere.
Clubul Presei
the press club is situated in the basement of the gulliver block first tall building on the stefan cel mare boulevard starting from piata unirii, on the side opposite to the main street. look for the yellow door with the ramp leading to it. though not exactly a metal bar, it's a meeting point for metalheads and other alternative types, since it serves some of the best mulled wine in iasi. you might want to stick to the small serving, though. it can make you much tipsier than you'd think. if you want to play it safe, go for their special, brandy-and-whipped cream hot chocolate. oh, and try to avoid the toilets. if you've lived in, or traveled extensively through eastern europe you've seen much worse, but there's still no need to subject yourself to that mess.
