This is somewhat of a tangent, but free lunch is a very important perk for me (note: I don't work at Google). For $15 a day, I could order in food every day and effectively have free lunch, wherever I worked. But I also wouldn't - in the back of my mind, I'd know that the $90 could be used to go and see the opera or a Broadway show, so I'd cook, or go and eat at Subway or whatever. So I'm not sure what I value that perk at, but I think just not having to even think about the lunch part of my day is important. I would weigh this as a positive, say a $5000 benefit.

The company that I work at has "no vacation policy". Honestly, that makes me the most hesitant, and to be honest, I don't really like that policy. However, senior management has been very good in two regards: they take vacations, and they encourage people to take vacations. So it does seem to work out. We're small right now, so it works, but I could see it being very easy to get wrong.
