There are many options available for you. In what area would you like to be located?
I  don't mind the area.
I recommend the Allenbell guesthouse. It's 4 stars, but cheap! 
What's the address there, please. 
The address is 517a coldham lane. Do you need anything else?

Did you need help finding information on restaurants?
Yes, I'd like something cheap in the centre.
i have 15 cheap restaurants in that area. what is your preferred food?
I don't have a preference for food. Anything is fine. Just cheap and in the Centre.
I recommend the golden house, if you like Chinese. I'd be happy to book a table for you.
