I needn't have worried. It was beyond my expectations. The sourdough was perfectly soft, the cheese was perfectly stringy and the sauce perfectly delicious. In fact at the time I declared it to be the best pizza I ever had, though it's been so long now that I can't remember if this is true or if I was just very hungry (as one often gets when on a long pilgrimage). The ingredients are all sourced from Naples and slow cooked in a stone oven - according to the owners electricity kills pizza - so there really is no hope of recreating this at home.
I recently decided to torture myself even further and see what I missed out on from the restaurant menu. Aside from a large variety of other pizza toppings, I also missed out on mini deep fried calzones, tomato risotto balls filled with smoked mozzarella and most upsettingly, deep-fried Italian mac n cheese. Most intriguingly though was a recent addition to their Exmouth Market stall - pizza soup and a dipping calzone to go with it. Genius. I believe another pizza pilgrimage shall be in order.
