I'm looking for a moderately priced restaurant in the centre. Can you recommend one?
Sure, I can help you with that.  There are plenty of options that meet your requirements.  Was there a particular type of food you were interested in? 
Are there any Australian restaurants?
I'm sorry, there are no Australian restaurants in any price range anywhere in Cambridge. Would you like to try a different cuisine?
What about European?
There are four great choices but i highly recommend galleria located at 33 Bridge Street. Would you like me to reserve you a table?
Yes can you please make me a reservation?
Sure. What day works for you?  How many people will be in your dining group?
Just me. And I need the reservation for Wednesday. 
Sure, what time do you prefer? 
Make it for 11:15.
Ok, your booking was successful. The table will be reserved for 15 minutes. Your reference number is : JFF6XGYL.
Thanks I also need a hotel to stay at with free parking in the same area as the restaurant. 
alexander bed and breakfast is quite popular in the centre of town and while on the cheap price range, it is a 4 star which includes both internet and parking.
I am actually looking for a hotel to book, not a guesthouse. I need a hotel in the center with free parking.
I have 2 to choose from. The Gonville Hotel which has 3 stars or the University Arms Hotel that is 4 star rated. Do you need a reservation at one?
Lets book the Gonville Hotel.
How many days would you like to stay?
I need a reservation just for myself for 3 nights starting Wednesday, please.
OK, booking complete at the Gonville Hotel for 3 nights starting on Wednesday for 1 guest. Your Reference number is : 9QUHR157.
Thank you for all your help.
Have a nice day, goodbye!
