We have some friends here with their 15 year old son and they would like to take him to a pub one evening. He doesn't want to drink alcohol, he'll be with his parents and they will eat a meal.
I thought this was ok from the age of 14 and I understand that some pubs will have their own policies especially on weekend nights.
So I'm happy to ring around a few places to see what their policy is but I'd feel more comfortable knowing the law beforehand.
