Task-oriented dialogue about: restaurant

I need to get to a restaurant known as the Lucky star
It is located at Cambridge Leisure Park Clifton Way Cherry Hinton.
Thanks, please make a reservation there for 2 people at 18:00 on saturday.
I'm sorry, but there are no tables available at that time. Would you like to choose another day or time?
Sure, do they have any openings at 17:00?
Thank you goodbye
