Very nice venue, however you're required to purchase tokens which can then be exchanged at the bar / food stalls, which inevitably means you have tokens left over at the end of the night. You could also only purchase tokens in quantities of 4.5 as a minimum, when a pint of Heineken is 2 tokens, which would leave you with .5 tokens left after buying 2 pints. A clear and frustrating money making scheme for the venue, taking advantage of the customers situation.
