In between dishing on the usual snark suspects, industry gossip site Eater is actually telling readers how they can put a little social justice on their tabs today.

See, March 22 is World Water Day, and New York City diners can help. The Tap Project, run through UNICEF, is asking NYC restaurant-goers to add a buck to their checks at participating restaurants today.
