U: I'm planning to visit Cambridge and would like to know the options available for upscale Chinese dining.

S: I have several recomendations. Would you care to try Yu Garden? It has great Chinese food, but is expensive.

U: Does it have free wifi for customers that are eating there?

S: Yu Garden does not offer free WiFi? Would you still like to make a reservation at the Yu Garden?

U: I don't mind an expensive restaurant so that will be fine.  I would like to reserve a table for 3 on Sunday at 15:00.

S: How about yu garden? It's expensive and serves chinese food.

U: Does Yu Garden have high chairs for babies?

S: At this time high chairs are not available at Yu Garden. Would you like me to try to book a different date or time?

U: That should be fine. Can you get the reference number?

S: Unfortunately there are no reservations left at that time. Would you like to change the restaurant?

U: Does the restaurant serve alcohol?
S: Yes, Yu Garden does serve alcoholic beverages and with high marks for both food and drinks. Would you like to know more about them?
