The McBarge, officially named the Friendship 500, was a McDonald's restaurant, built on a barge for Expo '86 in Vancouver, British Columbia. Moored on Expo grounds in Vancouver's False Creek, it was the second floating McDonald's location in the world (the first being in St Louis, Missouri), intended to showcase future technology and architecture. Although the floating design allowed for the barge to operate in a new location following the exhibition, the derelict McBarge has been anchored empty in Burrard Inlet since 1991, amid industrial barges and an oil refinery.
Disused and forgotten for years, the barge was the centrepiece of a failed proposal for a waterfront development on the Fraser River in Mission, British Columbia, including a restaurant and marina.
