Sure, but Red Lobster should be able to make ends meet paying that rent. Their accountants should run the numbers and have numbers for what the restaurant made after paying rent, and what the real estate investment made from rent. Even though the same entity owns both they still need to know where the money is. If a restaurant cannot make money except that the real estate is paid off and thus rent free (or maybe bought at lower than current prices and so payments are artificially low) then they should close and rent the real estate out to someone else.
The above is something people often fail to think of. If you (as is common) have something that could be two independent business with one supplying the other, then you should have your accountants figure out the numbers for each separately. (this is not easy, and eventually not worth it)
That's not so clear to me. The real estate wouldn't have been worth so much without the existing restaurants having to pay rent.
