There is a free McDonald’s restaurant in the corporate headquarters, but there’s also a deli counter which has fresh sandwiches, as well as a counter for other hot meals (chilli, chicken curry (UK) etc.

I used to work at the corporate headquarters of a company that owns several chain restaurants. The cafeteria there didn't have any of the chain food dishes, but was very high quality as far as office cafeterias go. They had a test kitchen there also and sometimes they'd give out free meals of the stuff they were testing.
