Father's day is approaching! What activities would you recommend on father's day?

I won't be seeing my dad this year for Father's Day as I am currently based overseas but I plan to have a Skype brunch date with him (and my mom). If I were at home, I'd probably take my dad somewhere awesome for lunch or dinner. My dad is quite a foodie but he is also diabetic, so it's quite hard for him to enjoy meals outside. I'll research restaurants and take him somewhere he can enjoy his meals without worries :)
