Task-oriented dialogue about: restaurant

Hello. Could you help me locate a good moderate restaurant in the south of the city?
There are 2 options. Pizza hut cherry hinton serves Italian food and Restaurant alimentum serves modern European food.
Do you have anyplace that serves Chinese food?
I'm sorry, there are no Chinese restaurants located in the south that is moderately priced.
OK I will go with Italian food and pick the Pizza hut cherry hinton. Thank you for your help.
Would you like me to book that for you?
Yes, please book a table for 4 people at 19:00 on Sunday. Thank you.
Booking was unfortunately unsuccessful. Can we try another day or a differen't time slot?
How about 18:00?
