Which fast food restaurant has the best value meals?

So far, I loved Wendy's 4 for $4 menu! A Jr. Classic Bacon Cheese, small fries, 4 nuggets, and a small drink. It's pretty much the best bang for the buck, that other chains are copying.
Burger King, on the other hand, while quality may vary, may steal this away. I enjoy their 2 for $5 all year. Despite being a ripoff of McDonalds deal that's only seasonal, it's still in effect all year.
So OT, what are the best deals in your favorite fast food restaurant?

Any help appreciated.

I didn't find the right solution from the Internet.
