When I was living in San Diego I'd say I spent about the same - easy $800 - $1000 per month. Use to take people there for lunch and dinner almost on a daily basis! They ALL knew me! Saki John, the main chef - used to hook me up EVERY TIME!
The place is called the Sushi House and it's near Encenitas ... best seafood salad with all kinds of sashimi, shrimp, octopus, cucumbers and special sauce! MMMMMM GOOD!
Also LOVE the Albacore Special Roll and the Crunchy Roll with Tempura Shrimp and Eel sauce ... sure the rice fills you up .. so what? The rolls are off the fuckin' chain!
One of the many things I miss about Dan Diego!
