The band played at London's Koko venue earlier this month and their management contacted the head chef at Camden's Gilgamesh restaurant to supply the food.
Chef Ian Pengelley told British newspaper the Daily Mirror: 'I was in the middle of cooking for 300 restaurant customers when I took the call.
'We were already flat out with orders, but we still managed to rustle up a feast for the guys.'
Frontman Anthony Kiedis and the group ate food including stir fried spicy Asian greens, jasmine rice and black cod.
