Food for bride & groom

The biggest thing being told to my fiancé and I is that we won’t be able to eat at reception much and to designate someone to ensure there is food for us to take afterward. If anyone else has something like this that they’re doing, I’m just curious if you’re bringing leftover containers for your venue to fill or if you’ve already talked to your venue about it, and they are supplying boxes. We have our meeting with our venue next month, and it’s one of the questions I plan to ask them, but I was just generally curious at this point.
