Here's The Burger King "King Deals" Weekday Lineup. I Jotted Them Down To Share With You Along With My Thoughts On This Advertisement Campaign.

Here is the weekday King Deals lineup (taken from the daily billboard ad):
Monday Tender Crisp
Tuesday  Original Chicken Sandwich
Wednesday  Whopper
Thursday  5 Piece Chicken Strips
Friday  Premium Alaskan Fish

I think ads with a catch phrase catch my attention. I like referring to Whopper Wednesday, doesn't that roll off of your tongue nicely when you say that. The other one that could have potential is the item for Friday. I would cut out the Premium Alaskan and just call it Fish Friday that is more catchy when you refer to it in that manner. These are just my thoughts and observations. If you give it a short catch phrase it is simpler to remember on that day of the week. Would you easily remember Fish Friday or Premium Alaskan Fish on Friday? See what I mean.
What about the weekend? Maybe extend the deals throughout the weekend but do not feature lunch and dinner items. What about featuring breakfast deals on Saturday and Sunday? Why not take it a step further and extend your breakfast menu hours to accommodate those that enjoy breakfast anytime during the day? It seems to be the cut off time for breakfast at "to go" fast food restaurants is around 10:30 AM. Why not extend it on the weekend and then feature a certain breakfast deal on each day of the weekend and just offer that deal during the extended hours for breakfast. Do not keep the entire breakfast menu up and running just allow the featured deal on that day for breakfast to be offered until maybe 2:00PM or so. Some people do enjoy breakfast anytime. What about you.
Again, Burger King this is a clever campaign advertisement. Scattering the general billboard ads throughout the area and then capturing your attention with the electronic billboards giving the daily details. It caught my attention enough so to seek out daily for one full week the billboard to be able to write down the daily featured deal.
