i need to find a place to stay in the east side
I have 7 such places to stay. Is there a specific price point you would like to stay in or do you need parking and/or wifi?
I need a room in the expensive price range.
I think you would enjoy Express by Holiday Inn Cambridge. 
I'd also like it to have a 4 star rating.
Unfortunately, I do not happen to have anything 4-star rated that is expensive and in the east. Would you like me to try a different price range or area? 
Yes, can you try a moderately priced place instead? 
I would recommend A and B Guest House.  It fits your criteria except it is in a moderate price range.
That sounds great! May I have their address, please?
A and B guest house is on 124 tenison road, cb12dp. Can I help you with anything else?
Thank you.  Also I am looking for the address of a place called williams art and antiques.  
I found that for you.  It is located at gwydir street, no. 5 dale's brewery and their phone number is 01223311687.
Thanks. I would like a taxi to commute between the two places. 
Certainly.  Would time would you like to leave and arrive at your destination.
I just need to leave the hotel by 03:45.
Your ride has been booked, it will be a white bmw. Call 07514195379 if you have any further questions.
OK, thanks. That's all I need today! 
Thank you for contacting Cambridge TownInfo centre. Goodbye!
