Waiter: Good evening. What can I get you today?

Mark's mum: We'd like rice with some pork cooked in fish sauce. Oh, could we also have an order of roast chicken and fried vegetables?

Mark: And I'd like some fried tofu and spring rolls too.

Waiter: OK. Would you like any canh? It's a kind of Vietnamese soup. We often have it with rice.

Mark's dad: Let me see ... I think we'll try some canh.

Waiter: With shrimp or fish?

Mark's dad: With shrimp, please.

Waiter: Would you like anything to drink? We have a lot of drinks: juice, lemonade, green tea, mineral water, ... Mark's mum: Mineral water for me, green tea for my husband, and juice for my children.

Waiter: What kind of juice would you like?

Mark's sister: Do you have winter melon juice?

Waiter: Let me see. Er, yes. How many cans would you like?

Mark's sister: One ... No, wait, two please. By the way, how much is a can of winter melon juice?

Mark: The menu says it's 10,000 dong. Waiter: That's right. I'll be right back with your order.
