There was a company lunchroom/cafeteria at a company at which I worked. It was pretty basic. They mostly sold drinks and pre-made sandwiches,salads, and desserts. Many people brought their lunches but ate in the lunchroom. Sometimes people talked about non-work topics or played cards, but people generally liked their work and “talked shop.” It was a place to meet people from other departments and where cross-fertilization of ideas occurred.
It could be that they don't want the workers to share what they have been up to.
