Sunny - I'll not comment on specific places in Ireland, you have to know where to go ....... What's with 2 am, I though Irish pubs closed at 11 or 12 - what are the licencing laws now?
I will never forget being on 3 day honeymoon in Dublin (all we could afford - in the days when you paid with savings for your wedding etc and didn't borrow it on the credit card - didn't have credit card come to think of it) and getting a drink, literally 1 second later, lights on, bell ringing, tables up and out on the street, mega shock, spent 2 hours in thin clothes in the snow trying to get a taxi. Being a culchie didn't know you couldn't get a taxi did I. Had an aversion to Dublin ever since ! ! !
Now that I've had to get up EVERY Sat and Sun for 5 years I try to be in bed by midnight at the weekend - sad I know. Coincidentally I live somewhere where the Irish pub closes when the metros start at 6 am and you can buy beer in McD and every corner shop for that matter .......
