I make my own sushi sometimes as well, my favorite with the quail eggs is on top of masago (flying fish roe, little orange eggs), actually you only put the yolk (raw) on top of the masago. It is very easy to make: sushi rice on bottom wrapped with seaweed (rice only half way up seaweed) fill rest with masago and then put a quail egg yolk on top. I put a little soy sauce with wasabi on mine and then enjoy. The creaminess of the yolk with the masago is absolute heaven.
Fontana is outside LA about 50 miles, it is in the Inland Empire. I live near the CA speedway where the NASCAR races are held here in SoCal.
