The attacks started at a Taco Time, which at the time had an open-air salsa bar. The attackers referred to their goo as "salsa" and their plan was to contaminate the salsa bar. After they got away with the initial attack, they expanded to salad bars, water sources, and other open-air offerings at restaurants.

Taco Time still exists, and even that particular Taco Time is still open, but they now keep the salsa tanks closed to improve hygiene.

Wendys and Pizza Hut had them.
