Read the text and answer each question with a paragraph number(1-4)
1.The last time I went to a restaurant was about 2 months ago. My wife and I wanted to celebrate our wedding anniversary with a good meal so we went to an expensive Italian restaurant in downtown Lisbon. We both had pasta to start and for the main course my wife ordered a steak and I chose fish. For dessert we both ate chocolate cake topped with fresh cream. Delicious!
2. I went to a restaurant yesterday evening with my sister's children. It wasn't very expensive and the menu was very limited. We all had a burger and French fries, and drank cola. It wasn't very good.
3. My friend loves spicy food so this restaurant was perfect. The waiters were all really friendly and polite, and they played traditional sitar music which was very relaxing. The menu offered vegetarian dishes as well as meat dishes served with rice and a sauce -it depended on how hot you wanted it! I chose a mild beef curry but my friend had a lamb 'vindaloo' -he also drank 2 liters of water!!
4. My class at the university went there last weekend. It's a very popular type of restaurant in my country. It generally offers one type of food (a kind of bread with cheese and tomato sauce) which you then choose what ingredients to add on top of it. I asked for olives and mushrooms on mine and my classmates each had something different so we could taste a piece of each person's meal.
