How about a cookbook with authentic Greek recipes that your dad can try out in the kitchen? You could pair it with some high-quality ingredients, such as authentic Greek olive oil, feta cheese, and kalamata olives. Or, you could also consider taking your dad out to a nice Greek restaurant where you can enjoy a meal together and experience some new dishes. Another option could be to arrange a Greek cooking class or food tour in your area.
Or you can get him a star map with the date when he was born.
