There are several for you to choose from. What kind of food would you like? Really, there are too many to list. I would recommend a nice Chinese restaurant like Charlie Chan.
Cheap restaurant in the centre, please. What kind of options do I have in that area? Okay. That sounds good. Can you book me a table for 1 at 13:00 on tuesday?

Unfortunately there is no availability on Tuesday at 13:00. Would you like me to try to book at another time?
