Peterborough, due to its large Italian immigrant population, is the crucible of the UK pizza house. One of its most famous residents is Peter Boizot, founder of the Pizza Express chain of restaurants. Oddly, Peterborough is only now getting a branch of this chain.
But the oldest pizza restaurant in the city, started in 1980, is the Pizza House, in Cowgate, right in the heart of the city centre. It's a cafe-style pizza house, still owned and run by an Italian family, and pre-dates the invasion by US pizza chains and even Pizza Express.
Posh pizza 'posh' being the nick-name of the local soccer team as well as meaning top-quality is served in many establishments, most notably Gastons, next to the Broadway Theatre
Another Italian restaurant well worth a visit is Riva, the cafe-bar adjoining the city's other theatre, The Key Theatre. Here, there is a bigger range of Italian cuisine.
There are a vast number of 'takeaway' restaurants but if you'd like to eat quality fish and chips, English style, try Parrotts Fish Parlour near the market, where you can sit down and much in relative comfort.
