Doubt about Sentence

[GuilhermeRM]

''At Burger King, the hamburgers are very
similar to McDonald’s,except they are
slightly smaller and contain less fat.'' Why '' similar to McDonald's'' is a falty comparison if 's indicates hamburgers of McDonald?

[fighting spirit]

Hamburgers of McDonald company, that is McDonald's hamburgers.

[charliedeut]

Except that the name of the company is "McDonald's", so it sould be McDonald's'. In order to avoid such messy writing, you could say "Similar to those at McDonald's".
