Do they take the time to go out? Do people bring lunch but eat in groups? Do folks normally eat at their desks because they're too busy to socialize? Asking this question serves as a great way to find out a little bit about the company culture. Plus, this is a more lighthearted question that might relax a stiffened atmosphere or lead to a conversation about shared interests.

Along with learning about company culture, it doesn't hurt to get a few good lunch suggestions for the future.
