PST: The large neon letters shining in the evening gloom spell out a very familiar welcome. And once you're inside, so do the sizzling pizzas with their rough-formed, carbon-flecked rims being pulled from the squat, no-nonsense, gunmetal-black, wood-fired oven. Anyone who has eaten at the original Pizza Studio Tamaki will feel very much at home at its new Roppongi spin-off.
