BB, does the creamy French have odd ingredients? It's hard to make a SF French dressing without adding some odd stuff.

Just watch out for Frankenfood, okay?
I've found that Blue Cheese and Ranch are usually okay in most restaurants, and so is Balsalmic Vinagrette, usually. Stay away from Italian and anything light or fat free in a restaurant; usually they are loaded with sugar.
On your own, you can find tons of dressings in the grocery store that fit the requirements.
One of my favorites is Annies Naturals' Tuscan Italian Dressing. No sugar and it tastes fantastic...especially on a salad with reduced fat feta!
