U: I'm not very good with numbers.  Can you tell me the travel time of that leg?

S: Travel time is 28 minutes. Would you like reservations?

U: No. Not interested in making a reservation but you can help me find a restaurant that serves Belgian food in the centre

S: I'm sorry, we don't have any Belgian restaurants. Would you like to try a different type?

U: How about African food?

S: We do have an african restaurant called Bedouin. It is located in the centre and is in the expensive price range. Would you like me to book a table?

U: Is the service worthwhile at Bedouin?
S: Unfortunately, there are more negative reviews of the service at the Bedouin than there are compliments about great service. It's a mixture of both types of reviews. Would you like to know more about the place?
