U: I am looking for a restaurant on the east side of Cambridge that serves Kosher food.

S: I'm sorry, there are no restaurants matching those specifications. Would you like to check a different area of town?

U: How about one in the same location with indian food?

S: There are 4 that meet your request. 2 are moderately priced and 2 are expensively priced. Does that work for you?

U: That works for me. Can you please book one of them for me for 8 people at 12:15 on Tuesday?

S: It doesn't look like like any of them have available reservations as that time for that many people. Would you like to look at a different time?

U: Can you check and see if any have availability for 11:15 and if they do book it and send me the reference number?

S: Great your reservation at Curry Prince is set, your reference number is G3GJE7ZP

U: Is the location nice?
S: The Curry Prince has a nice location in the heart of the city, but it's hard to find parking. What else can I help you with?
