Larry - You have to check out a place called SouthBeach in Ocean Beach at the end of Newport Ave - best fish tacos ever - try the Mahi or the Wahoo!! One of my favorites and a must-see for all of my San Diego visitors! They are nowhere near as gross as they sound!
An alternative (red meat) suggestion would be to have a burger at Rocky's in Pacific Beach, as seen in the movie Anchorman. Also a fantastic feast!
Learning as I go! Not stock, but doing as much as I can myself.
