Zizzi's - which have an extensive menu, of very good Italian food, so I don't have to choose pizza if I don't want it. I think the cost of piizza in a restaurant is not justified. Waitrose supermarkets stock Pizza Express pizza - so you get exactly the same food for a fraction of the restaurant price. Yesterday evening we had a pizza assembled to our own specification at Asda supermarket, took it home, popped it in the oven for 12 minutes. Cost £2.60. Bargain.
