ezPlatter Dietary needs are one of the easiest things to miss when ordering catering, and one of the most noticeable and uncomfortable things to get wrong once the event has already started and someone realizes there is nothing on the table they can actually eat. A short survey before you order solves most of this problem well before it becomes a real issue.
Send a dietary check-in with enough lead time
Ask about dietary needs at least 72 hours before a mid-size event, and about a full week ahead for a larger one. That window gives the restaurant genuine time to plan for specialty items properly instead of scrambling together something last minute the morning of the event. The common categories worth asking about directly, rather than leaving as an open-ended question, are vegetarian, vegan, gluten-free, halal, kosher, and nut allergies specifically, since these cover the large majority of real dietary needs you will encounter.
Expect a modest added cost, not a dramatic one
Specialized dietary options typically add $6 to $14 per person when the restaurant has enough notice to plan properly, which is a reasonable and predictable amount to budget for directly rather than something to avoid asking about out of cost concerns. Trying to skip this step to save a small amount of money usually costs more in goodwill than it saves in dollars.
Build inclusive options into the main order, not just a side table
Rather than a single separate "vegetarian option" set apart from everything else on its own small table, look for menu items that are naturally inclusive by design, like a vegetable wrap or a rice bowl base that different toppings can go on for everyone. This approach tends to feel far less like an afterthought, and it also gives more than one real choice to anyone with a restriction, rather than a single default item they are stuck with regardless of preference.
Ask about cross-contact, not just the ingredient list
For anyone with a serious allergy, the ingredient list alone is not actually enough information to make a safe decision. Ask the restaurant directly whether allergen items are prepared on shared equipment or in a shared fryer, since that detail matters just as much as what is technically listed as an ingredient in the dish itself. This is a specific question worth asking by name rather than assuming a general "no nuts" answer covers it.
A worked example: planning for a 40-person event
Say your dietary survey for a 40-person event comes back with 5 vegetarian requests, 2 vegan requests, and 1 gluten-free request, alongside 32 people with no restrictions. Rather than ordering 8 separate special meals, look for 2 to 3 dishes that naturally cover overlapping needs: a vegetable-based dish that is both vegetarian and vegan, plus a gluten-free side that works for the remaining request. This typically adds a modest premium (in the $6 to $14 per person range mentioned above, applied to roughly 8 people) rather than the cost of building entirely separate, one-off meals for each individual restriction.
Label the spread clearly at the event itself
Simple table cards or labels placed next to each tray, naming the dish and flagging common allergens directly on the label, save a significant amount of one-on-one questioning during the actual event and make it much easier for guests to serve themselves with real confidence rather than having to ask someone at every dish.
A simple pre-order checklist
- Send a dietary survey 3 to 7 days ahead depending on event size.
- Ask specifically about vegetarian, vegan, gluten-free, halal, kosher, and nut allergies rather than leaving it open-ended.
- For serious allergies, ask about cross-contact and shared equipment directly, not just ingredients.
- Look for menu items that cover multiple restrictions at once rather than ordering separate meals for each.
- Label the buffet clearly at the event so guests can serve themselves confidently.
Quick answers
What if someone discloses an allergy the day of the event? Check with the restaurant or caterer immediately about what is genuinely safe on the existing order, rather than guessing based on the menu description alone.
Is it rude to ask guests about dietary restrictions in advance? No, this is now a standard and expected part of event planning, and most guests appreciate being asked directly rather than having to bring it up themselves at the event. This pairs well with the headcount math in our food quantity guide.
Step by step: from survey to final order
Send the dietary survey with enough lead time for your event size. Collect responses and group them into the main categories: vegetarian, vegan, gluten-free, halal, kosher, allergies. Call the restaurant with these specific numbers, or check the full menu listing first rather than a vague description. Ask about cross-contact for any serious allergy. Confirm the final dietary-accommodated items appear correctly on the order confirmation before the event.
A second worked example: a small office of 15
For a 15-person office with 2 vegetarian requests and 1 gluten-free request, the added cost at $6 to $14 per person for those 3 people comes to roughly $18 to $42 extra on top of the base order, a small enough amount that it rarely changes the overall budget decision meaningfully, even though it makes a real difference to the people who would otherwise have nothing to eat.
Handling last-minute dietary requests gracefully
If a dietary need comes up the morning of the event with no time to adjust the order, check the existing menu items closely for anything that already happens to work, like a plain side dish or a naturally vegan item, rather than assuming nothing is available. Many standard catering menus have at least one or two items that quietly cover common restrictions even without a special request.
