With you on this one! It is was what I was after at the time as well. Id taken a photo of the stall during a morning stroll so I could remember to go back! Greenpeace Grill also did some incredible hash browns - something we were searching for in the morning for a while. There is certainly a need for a stall that specialises in just hash browns and potato tots!
Worst for me was Annie Maes mac and cheese, second time I’ve had it and I just don’t get it. It tastes weird to me, can’t put my finger on it.. I don’t love mustard so maybe it’s that?
