Questions 18-21
W: Tom, you have a good knowledge of Athens, don't you?
M: Well, I' ve been there a few times. Why do you ask?
W : I' m going to Paris on business next month. They told me I can spend one night in Athens on my way home. I' ve long been fascinated by the central city and want to make the best out of this coming night,you know, what' s your advice?
M: Your stay is short, but it still can be an unforgettable experience.
From my experience, you can take the new street car from the center of Athens to the Phaliron coast. It' s slow but delightful.
W: There must be a lot to see on the way.
M: Sure, when you get to the Phaliron coast, you have two choices. You can turn left for the Paratia.
W: What can I see there?
M: A strip of seaside nightclubs and famous Bazokiya.
W: Bazokiya?
M : Yes, there' re clubs with light Greek music, but I can' t tell you more about them. Because I turned right for the Peace and Friendship stadi-um. From there, walk half a mile, and you can see the greatest charming small harbor, Meiconomano. If you feel hungry, you can visit the Duringbay restaurant for the dinner of fresh fish and luxuri-ous salads.
W: Thank you, Tom.
M.. My pleasure.
