用英文对学校食堂提出建议

Dear Headmaster,I am a student of our school.I,d like to say something about the canteen service in our school. There are 3 advantages of canteen service in our school.First,our canteen is very clean,Second,the food is delicious,Third,the attitude of service is good. But it also has some disadvantages . Such as the price of the food is high, few variety to choose from,too long waiting time for buying food. In my opinion,we can invite our student to take part in the canteen for offering the help.We may let the student list the food they like to let the canteen to make it. I hope more and more student will like our canteen service.参考资料：帮助人我很快乐
