1. A visit to ArcelorMittal Orbit
If your dad watched everything - even the closing ceremony - at the Olympics, take him to explore Anish Kapoor's wild red sculpture which stands 115 metres tall as a reminder of the great event. On Father's Day, the first 50 dads get free entry; then it's £2 off for all other dads visiting with family. The East Twenty Bar & Kitchen next door will be doing a pie and a pint for a tenner, so you can make a day of it.
£11.95. www.arcelormittalorbit.com
