Person1: How did you enjoy your family party at " ginger ' s " ? I hear that they have a lovely menu and buffet .
Person2: Oh , it was great . We had seafood buffet . They do one every Friday . The waiters and waitresses are very good . They are very attentive , but don ' t hang around the table .
Person1: I like the buffets they have , but if often order a la carte , because I don ' t feel extremely hungry . I like the wine list there too .
Person2: Yes , so do I . they have wines from all over the world . There is a good range of prices to suit every pocket . We ordered some Australian red wine , which tasted delicious and wasn ' t expensive .
Person1: Some restaurants allow you to take your own wine and just charge you corkage , but the don ' t do that at " ginger ' s " . what was included in the seafood buffet ?
Person2: They had almost every kind of seafood . There were oyster , shrimp , prawns , crabs , and fish . I ate a lot of smoked salmon .
Person1: Did they have lobster ?
Person2: No , they didn ' t . you could order it from the menu . I think that lobster is too expensive to be included in the buffet .
Person1: Yes , it probably is . I don ' t like ordering oysters in restaurants . You never know whether they are fresh .
Person2: I know . I didn ' t eat any , but a few people in our group did and no one got sick .
Person1: When you eat out , do you usually eat from the buffet ?
Person2: Not usually . I usually just order a main course and have a dessert if I ' m still hungry afterwards .
Person1: Oh , you don ' t usually have a starter ?
Person2: No , I might have a soup if it ' s a cold winter day .

Person1: Where do we pay the fare ?
Person2: Just give the man sitting there three yuan and he'll give you a ticket .
Person1: Do I have to pay an additional fare to change trains ?
