Billy's Grill in Sherman Oaks has all of these, and more. I love their buffalo burger, no mayo. Comes on a nice, fresh roll with green leaf lettuce, tomato, kind of a 1000 island-type sauce, and grilled onion...so good!
Redondo Beach Cafe has both Buffalo and Ostrich. Rocky Cola Cafe in Hermosa has both Snax in Torrence has both Grinder in San Pedro has Buffalo Firehouse in Venice has Buffalo Broadway Deli in SM has Ostrich
