They are open to some special requests (e.g. vegetarian lunches, or
somesuch). However, they are also bound by framework agreements with
their suppliers, so they cannot just do as they/we please, at least
not without limits. We'd have to see when we have concrete requests.
We will need to ensure at least vegetarian, in my opinion.
All in all, I think this sounds like we can enter a contract and
then discuss details.
Their suggestion seems to be something we can work with, yes. I can't say I am thrilled, but that's in the nature of a compromise.
When do we need to define C and can C change for every day/meal?
