Here is a great tip on restaurant etiquette!

When making reservations to entertain a client – it doesn’t look good to show up at a great restaurant with business associate and not have made reservations to be there. If someone’s meal comes before you, it’s polite to wait until everyone is served — or you could graciously encourage then to begin.  Napkins go on laps — water and drinks on the right, napkins on left.  Avoid drinking alcohol — especially at lunch — long gone are the two martini lunches. It may only be appropriate at a reception or an event of that nature, but never over indulge under any circumstances.
