Prezzo are doing a new light choices menu which is brilliant. There is a choice of about 3 pastas and 3 pizzas. I had a vegetable pasta which was still a decent amount, there was a bowl of salad with it and dressing seperately. They say that all choices come in under 650 cals. It certainly didn't feel like a diet option to me and I would really recommend it. Have a look on their website for full details. Enjoy!
