At one restaurant -- Mike's American Grill -- the group had gone essentially unnoticed until a woman in her 20s with a satin-finished, stainless-steel revolver got up from her table.
The restaurant's manager spotted her and asked the group to either put the guns in their cars or leave. They left.
"When I saw the gun on her hip, I was like, 'What is going on here?'" said the manager, Gabba Kaye, who hadn't noticed the guns when the group of 20 checked in for their lunch reservation.
Kaye said he hadn't received complaints from customers, but that the weapons made him uncomfortable. He also said he had been warned by the restaurant's owners about the visit and instructed not to allow the group service while carrying.
