My parents live around the corner from the most wonderful Italian restaurant in Greenwich, London, which does the most delicious authentic pizzas, meaning that the pizzas are fired in a proper brick oven. One of them had ham, mushroom and five kinds of cheese. It was delicious!

Away from there, I usually eat Dominos pizzas. A bit pricey (£13.99 for a medium Meat Feast!) but they do good offers, and one can last me a couple of days, but essentially I spend one week's grocery money on one meal. :/

At least in the aforementioned restaurant 'back home' you get value for money. And hot Italian waiters...
