Pizza wins on sharing and on price per person. Three 12 inch pizzas for £18 feeds more people than three burger meals will.
Burgers win when everyone wants their own thing. Two burger meals for £9 on Deal 5 is hard to beat for a pair.
If you cannot decide, Deal 4 puts both on the table, or the Drip Box gives you a burger, donner and tenders in one £10 box.
The Drip Burger settles the argument in a different way: a beef patty with donner on top.
