Catering will usually take up about 20% of your budget. Think about it: catering covers tasting appointments, rehearsal dinners, appetizers, main courses (for tons of people), service staff, plates, silverware, napkins, gratuity, and set-up/clean-up fees. If you’re serving speciality drinks, this also covers the server, the drinks, and cups or glasses. Also, the more people you’re planning to serve, the more money you’ll spend on catering.
