The occasion nobody mentioned
A table for two on a Thursday might be a quiet dinner or a tenth anniversary, and you will not be told unless you ask. That difference determines how much they spend, how they remember the evening, and whether they come back — and most restaurants find out when the bill arrives, if at all.
Ask on every booking, in one sentence
"Is it a special occasion?" takes two seconds and surfaces something on a surprising share of bookings. People do not volunteer it — they assume you do not care, or they feel awkward announcing their own birthday. Asked casually as part of taking the booking, almost everybody answers, and you have just turned an ordinary cover into one you can do something with.
What it changes
A proposal next to the service station is a story they will tell, and not the one you want.
Celebration tables order differently. Knowing in advance means the right suggestions at the right moment.
A candle, a written plate, a chilled bottle. Small, cheap, and remembered for years.
Nobody wants an anniversary rushed for a turn.
The quiet requests that matter more
The same question surfaces things people find genuinely difficult to raise: a wheelchair, a hearing difficulty and a wish not to be seated near the music, a child who needs to be somewhere specific, a first date and a preference not to be in the window. None of these will be volunteered on a booking form, several of them determine whether the evening works at all, and every one is easy to accommodate given notice and impossible to fix at the door.
Capturing it is only half
A note about an anniversary that nobody reads before service is worse than not asking, because the couple mentioned it and were met with nothing. If you are going to ask, the answer has to reach whoever is running the room that night, attached to the booking rather than remembered. That is a small operational habit and it is the entire difference between the question being charming and being a broken promise.
Frequently asked
On every booking. People do not volunteer it — they assume you do not care or feel awkward announcing their own birthday — but asked casually, almost everybody answers.
Where they sit, what they spend, whether anything small is prepared, and how the service is paced. A proposal next to the service station is the wrong story.
Accessibility needs, hearing difficulties, seating preferences — things people find hard to raise and which are easy to accommodate with notice and impossible to fix at the door.
Asking and then not acting. A couple who mentioned their anniversary and were met with nothing are worse off than if you had never asked.
