What food will Chau and Liam have before the show?

Script:

Chau: Hey, Liam. Are you busy this Sunday?

Liam: Let me see, Chau. Well, I’m going to have a meeting at the drama club from 8 a.m. to 4 p.m. After that time, I will be pretty open.

Tom:  Great! Luckily, I have two tickets for the Vietnamese water puppet show at Thang Long Theatre at 6 p.m. Would you like to join me?

Liam: Why not? I’m really keen on watching the puppeteers make the puppets move smoothly on the water. Will the show be about a Vietnamese festival?

Chau: No. Actually, it will be about a Vietnamese folk tale called Thang Bom.

Liam: Sounds cool. When will we meet before the show, Chau?

Chau: Let’s meet at about 5.15 p.m. If you don’t know where the theatre is, my father can drive us there.

Liam: Oh, couldn't be better! I’m not used to streets in Ha Noi.

Chau: And do you want to eat something like hamburgers or hot dogs?

Liam: Yes, of course. But I’d love to enjoy beef noodle soup. It’s healthier. Is it OK?

Chau: Sure. There’s a small restaurant near the theatre selling the best beef noodle soup.

Liam: That’s good. Anyway, thanks for your invitation.
