So I multiplied the $30/day by the 9,600 employees in Mountain View and New York by the 251 days Google is open every year. Remember that Google probably spends a lot more than this, because there are employees outside those offices, and because visitors are there all the time eating.

The grand total: By our guesstimate, Larry and Sergey are spending at least $72,288,000 per year to fill their workers' pie-holes. How can they afford to do that? Easy, of course: Last year Google (GOOG) earned $4.2 billion.
