Calls over the weekend to other restaurant chains in the report were not immediately returned.
The report recommends restaurants:
Reformulate their menu items to reduce calories, saturated and trans fat, and salt, and add more healthy items like fruits, vegetables, and whole grains.
Make fruit or vegetables and low-fat milk or water the default sides instead of French fries and soda for children's meals.
Provide nutrition on menus and menu boards. New York and San Francisco are among the cities and localities that have adopted menu labeling policies.
Other restaurant chains included in the report are Wendy's, Dairy Queen, Arby's and Denny's.
Six leading restaurant chains -- Applebee's, TGIFriday's, Outback Steakhouse, Olive Garden, Red Lobster and IHOP (International House of Pancakes) -- weren't included in the report because they do not disclose nutrition information about their meals even when asked, the center said.
