What does the quote include?
Ask whether staffing, tableware, travel, setup and clearing are included or itemised separately. A clear breakdown makes it much easier to compare proposals on equal terms.
How will dietary requirements be handled?
Discuss when guest information is needed, how allergens are managed and whether alternative dishes will match the style of the wider menu.
What does the venue need to provide?
Some venues have a full kitchen; others offer only a preparation space. Confirm power, water, access, refrigeration and loading arrangements before the menu is finalised.
Who coordinates service on the day?
Know who your main contact will be, how the catering team works with the venue and other suppliers, and when the final schedule will be agreed.
