I'm a big fan of group meals and I've seen a fair amount of camaraderie built this way. That said, this reminds me of a team based PM course I was in a few years ago. Our group was made up of about a dozen people from different disciplines and we were asked "How do you know someone is being friendly to you?"
Most people had pretty common answers ("A smile, a greeting, etc") but one engineer said something that really confused the class: "Just don't bother me." That answer instantly expanded my understanding of team interaction. He wasn't saying it to be rude-he sincerely meant that letting him concentrate on his own business was a sign of endearment.
Most people enjoy (or, at least, don't mind) the lunches, group activities, etc. but some people don't. The job of management is to cultivate a productive group environment. Whether this includes regular group activities or not depends upon the individuals in the group.
