Help with Japanese ordering at a restaurant?

Question:

How do I write all this in Japanese?

What would you like to order? I want to order chicken. Would you like a drink with that? Yes, I would like a drink. What do you want to drink? I would like some water. Is there anything else? No, there is nothing else. How is your meal? It's delicious, thank you. Would you like some dessert? Yes, I would like some pie.

Answer:

W: なにに なさいますか？
Y: チキン（or トリニクりょうり）がいいです。
W: おのみものは　いかがでしょうか？
Y：そうですね。
W: なにを　おもちいたしましょうか？
Y：みずが ほしいですが、ほかになにかありますか？
W: なにも ございません。(???????)

W: いかがでしたでしょうか？
Y: おいしかったです。 どうも。
W: デザートは おもちいたしますか？
Y: そうですね。　パイがいいですね。

To be honest, it's not good dialogue....
--> I would like some water. Is there anything else? No, there is nothing else.
