Greenhouse by Joost, though it's only operating until January 29, has certainly grabbed its share of food-blogging attention. It's a paragon of trendy design and coffee culture, but at its heart is a message of innovation and sustainability. The families day-tripping to Federation Square don't seem to mind it, either.
We stopped by for a drink after our lunch at Base Kamp - it proved a charming and novel space to do so on a sunny afternoon. Michael's flat white ($3.50) looked just like Ryan's, and my iced coffee ($4.50) was just dandy without the usual icecream.
To my surprise, most of the menu listed on the blackboard was vegetarian (at least on this day). The quiches and rolls are visible in a display case at the bar, along with a few cakes and slices. The hedgehog slice ($3.50) was smooth and rich, not grainy with sugar as they can be. The portion size was just right, though it was dwarfed by the mighty particle board it was served upon. (I've not minded the plank-as-platter approach in the past, but this seems like overkill!)
If it were a permanent fixture I'd probably only visit Greenhouse occasionally but it's certainly worth a drink, a gander, and a moment of thought before it 'instantly deconstructs, leaving not a single trace of waste', to paraphrase the official website.
