A friend of mine said that Nonna's had one of the best seafood pizzas that she's ever tasted and so came here for lunch and tried it for myself.. Nonna's restaurants is three different types of cuisines (italian, seafood and steakhouse) which are basically joined in seatings and you can sit anywhere and can order from any of the different menus they have.. the biggest restaurant in the Harbour Town precint, Gold Coast..
