Google’s food bill
This article from Valleywag based on this Silicon Alley Insider article makes me laugh. It is mainly this comment:
“Dinner is probably served to a much smaller number of people, mostly single engineers who roll into work later in the morning. No matter if it’s free, after a while, you get tired of eating institutional grub three times a day and spending ten hours in the same office complex.”
That has not been my experience overall. People working in places like that do tend to take advantage of those perks more than you would guess. Ask Ackley about the FAIM dinner club and if everyone worked after eating. 
Also, from what I hear, the food is not very “institutional” by my standards.
Well- good for them. eBay’s food was not a perk but I enjoyed the people I ate with daily.
