As their "customers" sat down at arranged tables, the spunky duo tied pineapple tops to their heads and performed different acts based on their menu.
Food for eating, rather than wearing, was available as well - mostly English tea and sweets - but the participants were far more fascinated by the live art, including coordinated dance routines on top of tables to hysterical laughs.
After the comical pieces, members of the audience sat amused, digesting what they had just seen.
The idea behind the project is to create an interactive setting where the audience becomes part of the art or performance as soon as they step inside a venue - their reaction being an important contribution to the piece.
At this art cafe, visitors can experience the unusual exhibits and order a "three-course meal" of live art. Samples include Mum, a poem recital by Hunt; Cheese Toastie, a comical poem by Darton; and Victory, a series of triumphant shouts that one might expect from a winning athlete.
Strange, but without a doubt, entertaining.
In the same room, Tim Etchells, artistic director of Forced Entertainment, another performance art group, had his own exhibition running. It was an arrangement of posters with the repeated text: "Everything is under control." The display was meant to stimulate a reaction from the viewers, seeking to connect them to the artist, even in his absence.
More artists from the Forest Fringe performed.
Works included Someone Something Someone, a slow, choreographed performance of movement by Maria Sideri and Simone Kenyon; Time-Lab by Abigail Conway, in which participants could bring their own timepieces only to destroy them and rebuild them into works of art, symbolizing and toying with our perception of time; and The Redux Project, a series of popular film scenes amusingly re-created by Richard DeDominici.
With every exhibit, the events of Wednesday and Thursday gave Beijing residents a chance to familiarize themselves with performance art.
Such experiments help the artists involved to learn more about their peers, too, Field says.
