Yes, there are 5 different options to choose from. What area will you be staying in?
I don't have a particular area in mind but I do also need free parking please.
How about the hamilton lodge.  It is in the north of town and meets your requirements including parking.

Yes, I'm also looking for a cheap Chinese food restaurant. Can you recommend one? 
Sure, there are 4 options. I recommend charlie chan. would you like a booking?

Okay, the three results are the same. I still recommend charlie chan. Do you need more help today?
Yes, please book that restaurant for me. It'll be 7 people on wednesday at 14:45. I'll definitely need a reference number.
I'm sorry, I am unable to book it for that time. Do you have another time that will work?
