50ml is a newish addition to the Leederville coffee scene. By newish, I mean that it wasn't there when I moved from Perth to Canberra 18 months ago. It is open late, has quirky decor and although I had hot chocolate (which was okay), it looks like they'd serve decent coffee. They had a nice selection of cakes too, and some simple breakfast-y foods on the menu.
My photos came out red due to the lighting, but you get an idea of what it's like:
The lights are very cool, made out of red plastic baskets. Simple but quirky.
"toast $6, fruit toast $7, baked eggs $10"
Verdict? A great addition to the late night coffee / chill out scene in Leederville. A whole lot cosier and cuter than Greens & Co and San Churro which are its two main competitors.
