Today TGI FRIDAYS launches the "Endless Appetizers" summer promotion that offers all-you-can-eat appetizers for $10 per person. Guests can choose one appetizer from a list of the the chain's most poplar starters — including loaded potato skins, boneless buffalo wings and mozzarella sticks — and receive unlimited refills. And while sharing is discouraged, that rule will not be enforced by servers, says Brian Gies, chief marketing officer at Fridays.
