【正确答案】 Dear Sir or Madam,
I am a senior student of our university, who often have meals in our canteen. To be honest, our canteen provides a food service to students and staff that meets our nutritional needs. However, I still have some suggestions for you to make it more popular among students and staff.
Firstly, I wonder whether you could provide a range of food options that cater for a variety of dietary needs and rotates your menu on a regular basis. Many students have been tired of the regular menu. Besides, some students have always been complaining about the high prices of food there, so could you please reduce the prices a little bit to make the food more affordable to students?
I would appreciate you if you can take my suggestions into account and really hope that students and staff can enjoy having meals in our canteen. I'm looking forward to your early reply.
Yours sincerely,
Li Ming
