Nico's is what it is. It's your typical dive Pittsburgh bar. it's the Jacks of Bloomfield. I've never tried the food but the drinks are relatively cheap and it gets an awesome crowd that ranges from young hipsters to old yinzers. Rumor has it that it's the #1 karaoke bar in Pittsburgh so I recommend giving it a try one Saturday night. Whether your voice is terrific, mediocre or terrible, there is a great crowd more than happy to make you feel as though your voice really is terrific. It does get really crowded for Karaoke, so if you want to sing, make sure to sign up earlier in the evening (I believe karaoke starts at 9).
The only thing that I really dislike is that you can smoke in the bar.
