at dinner

At dinner one night, he told her about his idea for madcityhomes.com.

She could research things by herself, then show them off at dinner.

I was with my husband at dinner here last night.

But when they came to meet at dinner, her policy was quite another.

She knew nothing of the man who'd sat across from her at dinner the night before.

I didn't want to talk about what had happened at dinner.

I sat next to him at a dinner in 1986.

A few years later I sat across from her at a big dinner.

As a matter of fact, I was next to him at the last dinner before the rock hit us.

At dinner he could not speak without being heard by all.
