Hello dear @antorv,
Your workplace is really nice it is good to see that they provide discount on everything to there employee 😊.
Even when I visited to a place called delhi which is the capital of my country(India)"The specificity of a set lunch and dinner" was set by the restraunt and you can eat as much as you want. The price will won't change with the quantity you eat. And this thing was the best there.

Your office lunch set recalled my old days❤

Take care and happy shopping dear❤
