Hello from another Irishman in Argentina...

Hey everyone im Eamonn from Dublin, Ireland. Moving to Palermo soon to spend some time with my Portena girlfriend! I work in the field of language travel.

Where can you get a decent pint of Guinness in Buenos Aires??

Welcome on board Eamonn :)

There are plenty of Irish pubs in Microcentro but expect to pay a bunch of money for a Guiness.  It is far better to adapt to the local culture instead of paying to have one imported from home.  LOL It certainly save a lot of money.
