U: I need a cheap restaurant please.

S: Sure, I can help you with that. Do you prefer a specific area in town? Or maybe you'd like a certain kind of food?

U: Yes, portuguese food would be nice.

S: Nandos has restaurants in the south and the centre of town.  Would you like to book either of those?

U: Does it have various non-alcoholic drink options?
S: The majority of the customers were happy with the non-alcoholic drinks options while others found it to be limited. Would you like to know more about them?
