And one to avoid.
I've spent all my life around this city so what I'm about to write here I can categorically state is the absolute truth. Not an opinion, not hearsay or conjecture, the absolute according to Hoyle truth.
The smelliest location in Dublin City is outside AKA Bar, on Wicklow Street just up from Tower Records and opposite Brown Thomas. Not down the docks, not outside the fish market on a Monday morning, not in the Elephant house in Dublin Zoo. I have no idea why. Maybe it's an updraft vent from the sewers of Satan rising up here in all it's glory.
Whatever the reason, if you fancy a whiff of pure evil, it's here.
I'm not sure hugely why you would fancy a whiff of it but just in case the offer's there.
