After working together in Chicago and Paris, Feniger and her longtime collaborator, Mary Sue Milliken, settled in Los Angeles where they founded the critically acclaimed City Cafe in 1981. They eventually expanded to a larger space on La Brea Blvd., renaming the establishment CITY Restaurant. In 1985, they opened the Mexican restaurant Border Grill in the original City Cafe space, before moving it to Santa Monica in 1990. The restaurant later expanded to Pasadena (closed) and the Mandalay Bay Resort in Las Vegas. Broadening their culinary horizons Feniger and her partner opened the Latin flavor Ciudad in Los Angeles in 1998. The success of the three restaurants has often led Feniger and Milliken to be recognized for single-handedly changing LA's culinary landscape.
In April 2009, Feniger opened her first solo project Street, a multi-ethnic eatery of "street food" in Hollywood. Sample dishes include: millet puffs, paani puri, Massamum chicken curry, dumplings, Egyptian-style baked fish and peanut butter cookies for dessert.

In collaboration with Milliken and others, Feniger has published five cookbooks: City Cuisine (1989), Mesa Mexicana (1994), Cantina: The Best of Casual Mexican Cooking (Casual Cuisines of the World) (1996), Cooking with Too Hot Tamales (1997) and Mexican Cooking for Dummies (1999/2002).
Feniger is also a seasoned TV personality, starring with Milliken in 396 episodes of the popular Too Hot Tamales and Tamales World Tour on the Food Network in the 1990s. Prior to the shows on the Food Network, in 1993 Feniger and Milliken appeared with Julia Child in her PBS series Cooking with Master Chefs. Feniger has also appeared on Sabrina, the Teenage Witch and prepared with Milliken the food that was served in the 2001 movie, Tortilla Soup.
Most recently, Feniger appeared on the second season of Top Chef Masters that aired in 2010. She was the last female chef in the competition, eliminated following a challenge to create a dish fit for the gods. Feniger's creation for Aphrodite was Kaya toast served with a soy-glazed egg and coconut jam. She raised $32,500 for The Scleroderma Research Foundation.
