To be honest the main reason is that, even when the Pound was strong, Dublin was always a pricey place to drink. It always seemed better value to head East from Britain to either Holland (for obvious reasons) or the old Eastern Europe, where beer used to be the bank-breaking price of around 50 pence (compared to around £2.50 here) So yes, Damo, i am a cheapskate.
Now the Pound has collapsed the Irish (Republic) are keeping Northern Ireland's retail sector afloat with cross-border shopping trips.
Anyway, you won't be short of things to do and the locals will probably welcome tourists more enthusiastically than ever.
