W: Great ! Let's order quickly so we can chat a little.

M: OK. What are you in the mood for？

W: Something light. I went out for pizza at lunch and I'm still full.

M: There are three salads. Or you could have soup and a sandwich.

W: What are you having？ A hamburger, I suppose.

M: No, actually I ate out last night too, but we had fast food at McDonald's, then ate snack at Kentucky Fried Chicken.

W: Oh, dear. Well, maybe you should have the chicken salad.

M: Yes, I think so. Look, the daily special is spaghetti. That sounds good.

W: Oh, the prices are great, too. I'll have that as well.

M: Now let's decide on drinks.

W: I'll just have coffee and a glass of iced water.
