We usually go out to eat on the day of, but we go to a place that is never that busy so we don't have to worry about reservations or waiting for a table. This year, since it's Friday, my wife decided we would just get carry out from the same restaurant, and just eat at home, which is totally fine by me.
Also, I didn't get a chance to look at them, but I know that my oldest son took Super Mario Valentine's Day cards to his school today (Kindergarten). He was pretty excited about finding those since we've been playing Mario Odyssey lately.
