U: I am looking for Golden House restaurant.

S: Golden house serves cheap Chinese food in the centre of town.

U: Great. Would you book a table for 1 on Sunday at 12:00, please?

S: I am sorry but the Golden House was not available on Sunday at 12:00. Can I find another restaurant for you perhaps?

U: Sure, can you find me something close-by that has comparable prices? And can I get the reference number please?

S: I was able to get you in at Charlie Chan, another inexpensive Chinese restaurant in the centre. Reference number P4K1B3X6. Can I help you with anything else?

U: Does Charlie Chan serve sweet and sour pork that's a decent value?
S: Charlie Chan serves tasty food, however I am not sure exactly what type of food they serve. Do you want to know anything else?
