Task-oriented dialogue about: restaurant

Are there any Mexican restaurants in the centre?
Sorry no, there are no Mexican restaurants in the centre of town. Would you like to check another area?
Sure. I would be interested in Indian restaurants also.
Curry Garden is in that part of town and they serve Indian food.
Please book this for 7 people, at 18:00 on Sunday.
Unfortunately there is nothing available for 18:00 on Sunday. Would another date or time work for you?
Try 17:00 on Sunday.
Of course. You're booked at 17:00 with reference number TTP6GYCJ . The table will be reserved for 15 minutes. May I assist with anything else?
No, that'll do it! Thanks!
You're welcome, enjoy your meal.
