Catering for 100 people is a fundamentally different challenge from organising lunch for a team of 10. The logistics, dietary coverage, quantity calculation, and service format all scale in ways that catch inexperienced organisers off guard. Getting it right makes an event feel effortlessly well-managed. Getting it wrong — running out of food, not catering for dietary requirements, food safety failures — is remembered long after the event itself.
Dietary Requirements at Scale
In a group of 100 London professionals, statistical reality means you're almost certainly catering for: multiple vegetarians, at least one vegan, several people with halal requirements, one or two with gluten intolerance or coeliac disease, someone with a nut allergy, and several people with dairy intolerance. Planning for 5–10% of your group to have meaningful dietary requirements is a more accurate starting assumption than assuming a mixed London group is predominantly without requirements.
Collecting dietary requirements two weeks in advance — through a brief registration form or HR communication — allows accurate planning rather than reactive accommodation on the day. It's also a practical inclusion signal: you've thought about everyone before they arrive.
Quantity Planning
For a catered lunch where food is the main provision: plan for approximately 150–200g of protein per person, a generous portion of carbohydrate, and substantial vegetable content. For finger food receptions: 8–12 pieces per person for a two-hour event. Over-ordering by 10% is significantly less costly than under-ordering — the social and professional embarrassment of food running out midway through an event with 100 people present is disproportionate to the cost of modest surplus.
Buffet-style catering for large groups has a natural consumption variance — some people take considerably more than the planned average. Individual portion catering eliminates this variance and reduces both waste and the risk of popular items running out before everyone has eaten.
Service Format Considerations
For 100 people, the practical service options are: a staffed buffet (allows flexibility but creates queues and uneven consumption), individual box lunches (most controlled, eliminates queues, works well for working lunches), or a sit-down served meal (requires tables for 100 and significant service staff). The right choice depends on the event format — a working conference lunch benefits from individual boxes that don't disrupt the programme; a celebration is better served by a buffet or sit-down format that supports social interaction.
Working With a Caterer
For an event of 100, working with a professional caterer rather than ordering from multiple restaurant delivery platforms is strongly advisable. A dedicated caterer provides consistent quality across all 100 portions, professional presentation, reliable delivery timing, and accountability for dietary requirement management that fragmented ordering cannot. Briefing your caterer with confirmed numbers, dietary requirements, event timing, and service preferences at least one week in advance allows proper preparation at this scale.
Vanda's Kitchen for Large-Scale London Catering
