In March 2010, Congress passed a national law requiring chain restaurants, supermarkets, convenience stores, and similar food service establishments with 20 or more outlets to list calories on menus, menu boards, and for food on display [21 U.S.C. 343(q)(5)(H)].

Many states and localities have already implemented menu labeling laws, and restaurants have not experienced burdensome costs or negative effects on business.
