I had never seen purple mustard in my life. Until today, anyway. It's a pretty colour. Tastewise, it's not as spicy and edgy as I would have liked it but oh well, it's a novelty. Which was what drew B and I into the shop (ICON village), I suppose - we were at a bit of a loss as to where to grab a quick bite before our respective conference calls and the cute decor of the smallish joint caught our eye.
