RANKED: The top 10 restaurants on tech campuses, where employees chow down for free

With a huge variety of free or cheap food available at all times of the day, tech companies' cafeterias are arguably the best perk of all.

But which tech company has the best food? Foursquare helped us compile a list of the tech cafeterias with the most satisfied customers.

To determine the ranking, Foursquare's data science team used a set of algorithms to calculate a "sentiment score." The sentiment score represents how many likes a cafeteria received, as well as whether the tone of the tips were generally positive or negative.

The more positive the sentiment score, the better it did in Foursquare's ranking.

Foursquare's own Fat Denny's cafeteria was excluded from the analysis.
