U: Are there any cheap restaurants in the south part of town?

S: There are two choices in the South area serving cheap food. Do you prefer Portuguese or Chinese?

U: I do not have a preference.

S: Nandos is the Portuguese place, and The Lucky Star is Chinese.  Would you like more information on one or both of those?

U: Do they have great service?
S: Both The Lucky Star and Nandos has mixed reviews on their service. The reviews are similar with the service being slow and not as friendly as they would like. Would you like me to find a restaurant which is rated higher in service?
