Ted,
I am not going to comment on the dB aspect, but the XYL and I have had
great success in restaurants by asking the staff to turn down the music
(or TV or whatever was making electronic sound). In many restaurants,
it seems that the staff want to listen to *their* music over the din of
patrons voices, and that only makes the situation worse.
Lowering the music level will lower the overall noise level
considerably. People tend to talk louder in a setting where there is
loud audio background - they want to talk with their table partners over
the electronic noise.
I don't know how to counter the Holiday season when you have "Jingle
Bells" or "Grandma got run over by a Reindeer" blasting in your ears -
eat and shut up may be to only way to counter it or be branded as Grinch
or Scrooge.
Of course, there is always the one restaurant patron who has no concept
of "inside voices" that becomes an irritant to everyone else.
Choose restaurants with carpet instead of hard floors for a further
decrease in ambient noise level - soft wall hangings help too.

A very unpleasant dinner last night at a restaurant with a reported noise level
of 84 db – about the same as a gas engine lawn mower seated at the next table –
raised what is probably an elementary question. 3 db is the familiar doubling
of power, and in an audio environment is a doubling of acoustic energy, I
understand. However, I have read that ten db is what results in an apparent
doubling of the sound level as we hear it. Is the difference attributable to
something like an AGC circuit in the human auditory system? And as for RF
transmitter power, does it take a ten db increase rather than 3 to effect an
apparent doubling of audio amplitude in the ears on the other end of the QSO?
Never mind the S meter – I mean the actual ability to hear a signal over the
noise, or over the QRM. Help, anyone?
