Gino's Italian Restaurant in Des Moines, Iowa is known for their fabulous house salad dressing (a creamy Parmesan cheese dressing). This recipe is very close to their great recipe. I know you will be tempted to leave out the achovy paste, but DO NOT. It is what makes this salad dressing so special. Achovy paste is found in most grocery stores and is not expensive. This recipe makes a large batch, so I often make just half of it.
