We are always a bit last minute in our family for any celebrations. Here what I found for fathers' day present:
Present 1: Selfridges offers today and tomorrow a free engraving of any Moleskine's diary you buy at the stationary department on the ground floor. - an elegant and useful present. Just think of a nice quote and it is all you need.
Present 2: If you are more into experiences, this week-end it is a Taste of London Festival in Regents Park. Get a ticket as a present and enjoy a Sunday out tasting amazing food.
