The restaurant scene was filmed at West Hollywood's Ago, whose owner/investors include Robert De Niro and Christopher Walken and is known for its many celebrity sightings and Hollywood power-lunches.
The breakfast scene was filmed at the original Irv's Burgers on Santa Monica Blvd., a longtime West Hollywood favorite and former hangout of rock stars and local celebs. Though the building was granted historical status, Irv's has sadly been replaced by an upscale coffee shop.
