You can't use at weekends WHICH ISN'T IN THE SMALL PRINT SO BEWARE AS THIS IS EXTREMELY MISLEADING. You have to book in advance which, considering it's a fast food joint, is ridiculous. Ended up going Weds 1 Aug. Insufficient seating inside. The Fanta pump was dispensing carbonated water. Both the Coke and Coke Zero were completely flat. There was some confusion with the staff as to what was included in the deal. The 'Royal' is apparently excluded despite the fact it's the same price as everything else on the menu. The fact it was dead on a busy Wedsnesday afternoon probably tells you all you need to know. I'd rather have paid full price and gone somewhere else.
