Task-oriented dialogue about: restaurant

I need a cheap restaurant please.
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?
Yes, portuguese food would be nice.
Nandos has restaurants in the south and the centre of town. Would you like to book either of those?
Yes I would like to book Nandos in the south for 1 person at 15:30 on Monday.
I'm sorry, there are no tables available for Monday at 15:30. Would you like to try for a different day or time?
Can you see if they have an opening at 14:30 instead?
I made you a reservation at Nando's south, at 14:30 on Monday. The reference number is HB047XSI . They'll hold the table for 15 minutes. Do you need anything else?
No, that will be all. Thank you.
Thank you. Have a great day, goodbye.
