This is a great activity to have your students practice creating questions to ask classmates what foods they like/don't like. For this activity, they have to first write 5 original questions using gustar and food. Then, when you say, they go around and interview 5 classmates to have them answer their questions. There is an example question and answer to avoid any confusion.
If there is time in classwork, I have my students 'report' their classmate answers to me using 'le gusta/no le gusta...', either orally, or I assign it for homework.
