 I study at an ordinary secondary school. Like all other schools, it has a dining room (/a school canteen). It is large and light. There are large windows in the canteen. My friends and I always visit it. We can always buy delicious muffins, pies, juice, tea and various goodies in our canteen during our lunch break which lasts for 20 minutes. We can get there  different kinds of soup, vegetable salads if we like to, as well as various second courses which are different every day. To conclude, I should say, that we  are quite satisfied with our school canteen service.
Я учусь в обычной средней школе. Как и во всех других школах, здесь есть столовая (/Школьная столовая). Она большая и светлая. В столовой большие окна. Мы с друзьями всегда её посещаем. Мы всегда можем купить вкусные кексы, пироги, сок, чай и различные лакомства в нашей столовой во время обеденного перерыва, который длится 20 минут. Мы можем получить там различные виды супа, овощные салаты, если мы хотим, а также различные вторые блюда, которые отличаются каждый день. В заключение должен сказать, что мы вполне удовлетворены работой нашей школьной столовой.
