Interesting to compare with the valley. Google food and drink cost per employee per day was around $16 when I last heard. Dropbox was the highest around $60, although this was a few years ago.
How many meals does the average tech employee eat at work per day? My initial guess would be around 1.5, with the biggest meal of the day, dinner, usually being eaten outside of work. That would mean google spends more than twice as much per meal than cruises do.
