I’d like to say anything about the service in our school dining hall．In general，the service is satisfied．The hall is clean and tidy．And dishes look inviting and tastes good．What’s more，the workers there treat us as their friends，which makes us real happy．However，the cost of the meals was a little high．Also，we have only a limited variety of dish which are the same every day．In addition，we often have to stand with line for a long time after we get our food．This wastes a lot of time．I hope something can be done to solve about these problems soon．
