La Porchetta

Having grown up in Italy, I admit being a little picky when it comes to Italian food. La Porchetta will never get any Michelin stars but what they really do pretty well is the pizza. I still think it's one of the best to be found in London (but am always open to new suggestions!). Definitely try the one with pears and gorgonzola, it's simply to die for. The other great thing about the place is just how great the prices are. The house wine is decent and the staff (exclusively Italian) are extraordinarily friendly and cheerful (with groups of girls they sometimes are a little too cheerful and friendly...). The other downside (which for me, however, makes the place only more authentic) is the noise level - it's not a place for intimate conversations...
If the one close to Holborn is inconvenient for you, check out their outlets in Islington, Clerkenwell and Finsbury. Go to their website at http://www.laporchetta.co.uk/ to check out the menu. Buon appetito!
