Would be helpful if they gave an indication of how large those pizzas are and how much drink you get but frankly that might put more people off, especially if it's 8 inch pizzas and 330ml coke.
Edit: There's 42 calories in 100ml of Coca-cola so that works out at 380ml (before adding ice)

The pizzas look good in my eyes. One of those and a portion of chips and you have lunch for 2 for around £20ish. Could be worse!
