Hmm it's becoming less attractive as a proposition the more I read about it. I have loads of glasses at home, I don't need to buy another one, and certainly not for a tenner. So my first beer will essentially cost 3 times as much as 1 beer in any other bar in the city. Or to put it another way, I could go to ATG or B&C or PH and get 3 pints of Irish Craft beer for the same price as one here. Granted I may miss out on some special festival brew or something, but so be it.
Ah well.
