We expected this mobile coffee cart business to be on water,but no,instead it is transported to various farmers'markets by horsefloat - hence'afloat'. Matthew Beckwith and Alex Rigas run their fleet of three like well-oiled machines,fuelled by coffee roasted for them by Belaroma in Manly Vale. There's generally a fast moving line,a waste-no-time cashier and three or four baristas ready and waiting. A piccolo latte ($3.50) is well balanced and caramel-smooth but lacks a bit of kick,and kick is exactly what you need this early. There's no food,but really,nor should there be. You're at a farmers'market,remember.
