"You don’t know a great deal about this person, but you do at least know that you both like pizza. The great unifier. In that case, try Theo’s Pizzeria. This south London Neapolitan specialist is one of the best cool and casual restaurants in the city. Whether you’re heading to their Camberwell spot or their Elephant and Castle one, you’ll find an easy restaurant serving affordable, excellent pizzas, as well as affordable, excellent cocktails. Don’t leave without the tiramisu, even if you think you don’t like them." - Heidi Lauth Beasley, Jake Oliver, Sinead Cranna
