Hi Marc,
It's been a long time since I've done any restaurant gigs, but may I suggest a little light latin. Perhaps Petite Fleur (great on either clari or flute) Amapola, Spanish Eyes etc. And remember, most 4/4 songs can be played with a beguine feel - For the Good Times, I Wish you Love, Sunny etc. In restaurants, people don't always LISTEN to the music but they HEAR it; it's a bit subliminal. When people comment on the atmosphere of a restaurant, it's generally related to the "mood lighting" and the music, although neither are "in their faces"
Hope this helps, and good luck with the gig.


Cheers,
Keith
