Father's Day is the one day a year Dad gets taken somewhere he didn't pick, at a time he didn't choose, in a shirt someone else bought him. Least we can do is send him home with a beer.
Book a table for four or more online, everyone orders a main, and he walks out with a free 4-pack of whatever he actually drinks. Not a token stubby with the bill. Four cans, cold, his pick, in his hand on the way to the car.
One per table. The rest of the afternoon is his problem.
