Burger Shack is a fast food place that mostly serves burgers, Chili Fries and other associated food items, craved by both Ben and Albedo.
Kiddy meals can be given to children 8 and under.
Ben, Gwen, and Kevin often used to go there for a bite to eat when they weren't hanging out at Mr. Smoothy's.
Apparently, the franchise is popular among certain alien races, like Lewodans and Appoplexians, seen when both, who generally do not agree on everything, agreed to order takeout.
