It's also earned the distinction as the unhealthiest meal at a restaurant chain, according to the Center for Science In the Public Interest.. Aren't you curious what other restaurants made the list?The Cheesecake Factory is one of my favorite restaurants. Should you eat a daily diet of these high calorie foods? Obviously not but what's wrong with a high calorie splurge now and then? What's your favorite restaurant meal?
