Americanized sushi in the valley or hollywood??
Can't you get it just about anywhere? Most any sushi bar will serve you any number of fancy rolls and almost all have spicy everything, california, dragon, etc rolls.
For what it's worth, if a good sushi chef will do it, the best chefs tend to also make the best American style sushi as well. Your problem is if you ask for it, most good sushi chefs will have someone else make it for you.
