Ahhh, yes, this is one of my favourite places to go for "coffee" (as in usually anything but coffee). They've got a badass hot chocolate and chai latte, and their tea selection is outstanding. The real draw here though is the atmosphere: a small cozy industrial inspired room (literally - just one room) where intellectuals and freelancers gather to widdle the afternoon away.
Minor drawbacks: occasionally the music playing in the background evolves into Euro-dance. Also, word is getting out! Getting harder and harder to find a place to sit now. Let's hope the Mule doesn't turn into it's comrade Horse!
The owner, Peter, is pretty much as "real" as it gets. He is constantly welcoming regular customers with a smile, and his story is great, too. According to him, he quit his $$$ job, sold his house and all his cars, is renting out a much smaller place and making almost nothing running the Mule - but won't stop saying how much he loves his life now.
Now that's something to drink to.
