Task-oriented dialogue about: restaurant

I'm looking for a place to dine. The restaurant should serve japanese food and should be in the centre.
There is one restaurant called wagamama that fits your needs.
I'd like somewhere expensive, is it?
Yes it is.
Then that will be good. I need a reservation for 4 on Friday night please.
What time would you like to dine?
I'd like to eat at 17:30
