It's not just the main dishes that come in colossal serving sizes. Many restaurants serve meal-size appetizers that are cheaper and will still leave you full at the end of your meal. Another smart strategy is to have a small snack (apple, string cheese) at home before you go out so you're not completely starving. Just be sure to pick a restaurant that has plenty of appetizers to choose from. And hey, whoever said chips and dip isn't a meal?
