The "Carry Out Group" was met by supporters of the Brady campaign to prevent gun violence. The nation's event is part of the national rifle association's program to arm every American.
"We're educating them about their ability to hopefully carry a firearm that's unloaded on their person, you know, for the purposes of self defense should they be faced with a violent encounter," advocate Yin Chau-Chang said.
"Even though people do have a right to their self defense, I think that people certainly and communities can make sensible gun laws," Sue Davies from the Brady Campaign said.
The Brady Campaign has been successful in getting other bay area chains like Peet's Coffee and California Pizza Kitchen to adopt a "no guns' policy in their stores.
