Ballycolla is a crossroads in east Laois. It has a pub and a handful of houses. That is the settlement. Real and small and honest about it.
The Barrow Valley is nearby. Pass through on the way to somewhere. Have a pint if the pub is open. Keep moving.
None of these are themed Irish pubs, because they don't need to be. A few that earn the trip:
Open evenings. Check before you arrive.
East Laois, near the Kilkenny border. About 20 km south-east of Portlaoise.
No regular service.
