I need to find a hotel to stay in, some place with free parking. Thank you.
i have 29 options for you 
Okay, thank you! I would like a 4-star hotel.
That narrowed it down some, but we still have plenty of options available.  Is there anything else you're looking for like a certain price range or maybe internet?  
Any place in the south area of town?
I found two 4-star hotels in that area: Aylesbray Lodge Guest House and Rosa's Bed and Breakfast.
Yes the first hotel will do great, I need to book for 4 people and 2 nights starting from Tuesday.
Booking was successful. Reference number is : PZ6RF1H0. is there anything else i could help you with?
I would also like to find a pricey Gastropub, 
There are three expensive gastropub restaurants. Would you rather be in the centre or the east?
I would prefer the south.
Unfortunately the only restaurants that meet your criteria are in the centre or the east.
Can you look again? I thought I saw one in the south area the last time I was in town.
There are none in the south side of town.
Can you check all the gastropubs in town?
There are 4 gastropub restaurants in town. Three are located in the centre, one is in the east. Three are expensive, and one is moderate. 
I'm sorry, I need a restaurant in the south.
There are no gastropub restaurants in the south. Would you like a different kind of food?
Yes, let's try an Italian restaurant in the south, please. There should be one.
I have two Italian restaurants in south. We have the pizza hut cherry hinton and frankie and bennys. Which would you prefer?
I'll go with frankie and bennys. Do you have their phone number and address?
Yes. Their phone number is 01223412430 located Cambridge Leisure Park Clifton Way Cherry Hinton. Anything else?
Can you help me book a taxi?
I can book a taxi but I need to know where you need to be picked up and dropped off. Is there a certain time?
I need to leave the hotel by 6 and head to the restaurant.
I have booked you with a red honda taxi. Their phone number is 07534551524. Can I help with anything else?
No thank you, you were helpful
Thank you, any have a great day.
