Correction: they have 20 burgers with at least 500 calories in them. They have tons of other items with at least 500 calories in them as well. You can get over 2200 calories for a couple chicken tenders items. I used their own calculator for one meal:
1. Chicken salad.
2. Large fries
3. Large chocolate shake.
1880 calories.
Here's a different meal, double smokehouse burger, large fries, chocolate shake
2480 calories, 174% daily fat, 112% daily sodium, and that's just one meal.
