The best burger in Santa Monica is from Father’s Office. This place is a total disaster in terms of service (no list for tables, you basically dive on them when they open up), but it has to be in my top three burgers ever. They also have hundreds of beers and a TV playing local games.
Highly recomment it. More details at CitySearch.
