I live in the Monkland Village which, although is practical for me, is not exactly the most interesting neighbourhood in Montreal. This being said, MELK makes this neck of the woods 20% better to live in. True story.
The coffee (I almost always order the drip which believe it or not is fantastic) is so friggin' good that I can't make it on my own at home anymore. I literally gave up my $30/week fashion magazine habit for this coffee. It's THAT GOOD.
Oh yeah and they have the best scones in the entire universe. i used to hate scones and now I'm addicted to them and eat one about 4 times a week. Try the cranberry and dark chocolate one. It's AMAZING.
And finally the people who own it are cool and nice and unpretentious and love coffee. And they also like Bob Dylan and Johnny Cash and Vivaldi so the vibe in there is good.
DO IT!
