"Alongside the daily specials (rice, beans, meat — of course — for £7) Costa’s serves Brazilian pizzas and burgers. Pasteis are fried to order, perfectly blistered, the pulled chicken and molten catupiry a standout. The xburger — the letter x in Portuguese sounds roughly like cheese in English — may be London’s craziest burger. Stuffed into a collapsing bun are: a spicy patty, ham, melted cheese, lettuce, tomato, sweetcorn, and shoestring potatoes, which provide the same effect as the Walker’s in your school sandwich. It comes in a plastic bag, into which half the ingredients will fall. It is delicious." - Tomé Morrissy-Swan
