My dad is a foodie so I have planned to prepare a lavish meal for him that includes all his favorites. I am also planning to bake him a chocolate cake. Don’t worry about the extra calories for one day.
You can purchase a formal shirt or trouser that he can wear to his office. You can also buy any informal dress according to his choice.
If you want you can also gift him a personalized coffee mug that he can enjoy every morning. This can be a great gift and he will love it too.
