Make sure your guests can get there. However, to be successful, it is necessary to cover all the bases thoroughly, and organizing the catering well is essential. Even before you've considered your menu, more than 56 million people across the country have special dietary needs. So this can seem like a daunting task.
The 101 rule for how to serve a large group is to fix the numbers as soon as possible. A caterer will need to know them before they can give you an accurate quote. So be sure to create a guest list and request confirmation of attendance as soon as possible. That's why it's a good idea to opt for more food instead of less if your budget allows.
Trust your provider's judgment and experience about how much people usually eat at events. If you paid them to serve 400 diners, all 400 diners should leave the table satisfied. Depending on the type of catering you request, it may be necessary to organize a tasting before the event. This is more common in the case of sit-down meals or large-scale events.
Ask your food provider to prepare 3 to 5 different options for each dish so that you can try to choose a final menu from the selection.
