Whoa, 3-4 negative comments at the top already. If your employees are a bunch of single college-aged people who are already friends with one another, by all means eat together, play together, sleep together, do whatever else you want to do together. If your employees have their own families and social circles outside of work to care about, let them leave at 5:01. As usual, the important thing is to adapt to the needs of your people. When some of your employees get married, have kids, etc., you'll have to adapt accordingly. Problems arise when you refuse to adapt and try to impose the same culture on everyone. As long as you remember not to do that, I don't see any issues here.
