You can have any late night snacks delivered. Please let your caterer know your plans so they can set them out. Blizzards are always a hit (and info is in the google drive). Pizza of course is great too.
VERY IMPORTANT: If a late night snack is to be delivered make sure it has your specific venue name on it.
i.e. The BRIX - TWO-SIXTY or The BRIX - INDUSTRIA on the address.
It helps to include your name as the purchaser as well.
