U: I am looking for a cheap restaurant in the centre part of town.

S: You have lots of good cheap choices in that part of town!  What type of food sounds good to you? There are Italian restaurants, Indian, Spanish, Chinese, and more.

U: How about Chinese? can you book me a table for 3 people at 18:15 on a Sunday?

S: I'm sorry, none of the Chinese restaurants are available at that time. Is there another day or time that would work for you?

U: Ok, I'll try for a little earlier, how about 17:15?

S: Booked at Charlie Chan! Your table will be reserved for 15 minutes. Reference number is YGWCXMK4.

U: Are there good dumplings there and are they affordable?
S: Yes, past guests that have ordered the dumplings at Charlie Chan have said that the prices were affordable, and that the food was fantastic.
