We can seat you very soon.
Could you wait about 5 minutes, please?
Could you wait a little longer, please?
Could you wait in line until a table is free, please?
I'm afraid this table is reserved for 8 p.m.
We can seat 3 of you right away but if all your party would prefer to sit together, it will take about 15 minutes.
I'm very sorry to have kept you waiting, sir.
An escort will show you to your table. Just a moment, please.
Would you prefer a table near the window?
Would you prefer to sit at a table or at the bar?
