Task-oriented dialogue about: restaurant

Can you find me an italian restaurant in the centre?
Sure, there are 9 restaurants to choose from. Did you have a price range in mind?
I'm looking for something on the cheap side, please, although I'd like to get good value for the money.
There are three Italian restaurants in the center in the cheap range. They are pizza hut city centre, ask, and zizzi Cambridge. Which do you prefer?
Any of them will be fine. As long as it's cheap. I need a table for 4 on monday at 12:15 please.
I would recommend ask as it is a nice place.
Yes, please book ask for 4 people at 12:15 on monday.
I'm sorry but I couldn't book you there. How about another restaurant?
Yes please, same price range as before.
Okay I was able to get you into the Zizzi Cambridge and your reference number is GI0FZMKL .
Okay thank you very much for your help.
You are welcome. Enjoy your lunch.
Thank you. I will.
Okay. Don't hesitate to call us if you need anything else.
