I live in Ireland and whenever I travel I obviously try the local food and drink, but I also have to find an Irish pub and try the Guinness. In Cologne at the moment and the pint isn't too bad.

I have a scoring system out of 10:
Taste of the pint: +1 to +5
Owned by Irish: +1
Irish bar staff: +1
Authentic paraphernalia: +1
Good craic: +2
