It would be easy to say that you can’t go wrong with a pizza, but you can go wrong with a pizza. Very wrong. Take the tomato paste tortilla thing (topped with raw cheddar) we experienced in Budapest years ago. Pizza Pilgrims is a far better example of an affordable, good pizza. Dean Street is the original location of this Neapolitan pizza mini-chain and they’re still a go-to for chewy, thick-crusted pizzas with a thin and saucy centre. Their margherita is under a tenner or add a few more quid if you're after some other toppings.
