If you want your friends to eat healthier foods when you dine out, order FIRST. After analyzing nearly 1,500 receipts from people who ate meals together, researches from the University of Illinois at Urbana-Champaign, found that people gravitated toward similar meals when ordering in groups, even if they wouldn't naturally choose those dishes. So, order first and pick the salad to influence the group. This makes total sense to me. It's the same when you're ordering drinks... if you're out with some people and the first two people that order don't order an alcoholic beverage, you're probably not going to order an adult beverage. If you're out eating and first two people order crappy junk food, you may be more apt to join in the junkiness because you don't want to be the only one eating healthy. So, order first always to set whatever tone you want for YOU!
