I have essentially stopped wearing ties to work, except when I have to appear in Court, which sometimes is every day of the week if I am in a trial, or some weeks not at all. Even if I have a client meeting or a deposition of a witness, I usually don't wear a tie.
Several years ago I told my staff that they no longer have to dress for work, except if there is some special reason to do so. My paralegal (with me for 20 years) and my secretary (with me for 11 years) like this very much, and it saves them money on clothes, so essentially I gave them a raise that costs me nothing.
As for restaurants, I just follow the dress code of the restaurant. Here in Baltimore there are only a few places that require a tie.
