For the best pints in Dublin
I won't bore you with the horrible tourist bars that have no real culture in them (each to their own).
The best bars for a nice pint of Guinness:
1. The Foggy Dew (Dame Street)
2. The Cobblestone (Stonybatter)
3. Walshes (Manor Street)
there are others, but these show real Dublin, and real Dublin people.
This tip has the address "Dame Street / Stonybatter / Manor Street"
