Task-oriented dialogue about: restaurant

I need a moderate priced restaurant please.
There are 31 restaurants that fit your criteria. Is there a part of the city you would prefer?
I would like an Italian restaurant in the south.
I've found one restaurant. It is Pizza Hut Cherry Hinton. Would you like for me to book it for you?
Yes can you book for 6 people at 19:15 on Wednesday?
I cannot complete this booking. Would you like to find another restaurant?
That's disappointing. Is there anything else moderately priced in that area?
Yes, I also have the Restaurant Alimentum that serves modern european food. Would that work for you?
Sure, as long as it's in the south. Can you give me the reference number once booked?
I have reservations booked for 19:15 on Wednesday for 6 ppeople. The reference number is PJMAUG2E . Is there anything else I can help you with?
No, that will take care of it. Thank you very much for your help!
You're welcome. Enjoy your meal.
