I think either of those sites would be too big and expensive to run. Rents and rates on Mostyn St. are astronomical!
Also, and this is the view from the taxi, I believe people's habits have changed over the last decade. I find that people are going out much later these days, often as late as 11pm or midnight. They seem to prefer to have a drink at home first which is perfectly understandable given the prices of drinks in pubs.
You can pay £5 for a vodka in town or you can buy a bottle for £8.50 in Asda and have some friends round to share it! I know what I usually choose to do.
Whilst I'm generally against the Government's "minimum pricing" policy I do believe that closing the gap between the pubs and supermarkets could certainly help to get people into the bars (and taxis)!
I understand what you're saying, but there is much more to people staying at home than simply pricing.
I've recently moved back here from living in Liverpool and let me tell you that the pubs are busy up there any day of the week!
Because they are fun and have some genuine atmostphere - most Pubs in town these days are tourist bars by numbers, and are pretty boring. How many pubs in town have a jukebox these days? Not many, and for the ones that do they have it so quiet you'd have to have ears like Gary Lineker to get your moneys worth!! How many pubs have dart boards? Again not many, and most of the ones that do have it blocked by a bloody dinner table, so that they can cram even more tourists in and charge them more overpriced crap food.
I know if I stay at home with a few mates, I can put on some 'decent' music, have a few games of darts and a laugh. That's not something I can do in a pub these days!
Then though you get the old chicken before the egg scenario, because I probably met most of my friends through the years in pubs. If nobody's going out anymore nobody is socialising and that's got to be a bad thing!!
