Les 3 Minots is a small venue for live music, located on St-Laurent just north of the corner with Pine Avenue. The place is really small, so hearing live music there is an amazing experience: you're right in front of the band, right next to the musicians and to their equipment. This proximity to the artists makes the whole experience a very cozy one; it's basically like having a private show in your living room.
What's more, I found the place to be decorated with taste, with huge posters plastering the walls from top to bottom. Obviously there is a bar and there are tables, so the place becomes a friendly bar with good music after the live performances are over.
If you're an aspiring musician, or if you know some, I am sure you can call the bar to try to arrange a live show there.
