Hi all!
Its been a while. I know. But i have a question that has been driving me insane and nobody seems to know the answer. Hoping and praying that someone here can put me out of my misery.

What is the plural of McDonalds?

My friend says Mcdonalds's, but that doesn't sound right.

Please please please, somebody, anybody, HELP!
