As they were taken to their table he said "I always thought white looked really good on you." As far as Black Widow he didn't say anything else since Widow was a secret from the general public, at least Luke thought so. Just to be safe he kept quiet.

Once at the table Luke pulled out her chair like a gentleman and once she sat down he sat down in the other chair. When the waiter took their orders Luke ordered prime rib and scalloped potatoes. He also asked for a bottle of wine.
