Tips
If you're watching your weight, choose a baked potato, steamed vegetables or a side salad instead of french fries. If you do order fries, skip the chili, cheese, bacon and ranch dressing to save calories. Order a child-size version to reduce calories even further. Don't sprinkle your fries with salt.
