A party is never a party if food and drink are not involved. Attendees expect you to provide some sort of refreshment. Whether this is a full meal, or light refreshments, you can hire a food truck to cater for your guests. Food trucks have the benefit of offering warm meals, rather than catered food that is made in a massive batch and gets cold quickly. A food truck can also act as an open bar offering hot chocolate, coffee, and drinks throughout the evening.
