QSRs target the snack crowd

Palm BeachPost: Lunch is not just for lunch anymore. We've got Taco Bell pushing us to eat chalupas for the "fourth meal" of the day — the one that comes not between breakfast and dinner, but dinner and breakfast. Subway thinks its lunch subs are superb for supper. And now McDonald's wants us to pop in at noon for a Big Mac, then again at 2:30 p.m. for the new Snack Wrap.
