Jack reveals that the address of his restaurant ("Jack's Bistro") is at 834 Ocean Ave.
Ocean Avenue is indeed a major street in Santa Monica, which runs above the beach, and 834 would put it only a mile north of the Santa Monica Pier (where they filmed some of the opening credits).
However, 834 Ocean is on the WEST side of the street, and the west side of Ocean Avenue is taken up by Palisades Cliffside Park, a long, narrow strip of green parkland that runs along the Santa Monica coast. Since it's a public park, there are no restaurants or other commercial outlets located there.
