They missed a few places:
Restaurant Depot
Newport Meat
And if they’re including wholesale places that always sold to the public:
Universal Seafood
Port Town Foods
LAX-C
Daniels Western Meat Packers (via @Jase)
Does anybody know if Yoko’s Seafood sells to the public? It’s been on my list a while since they are unusual in publicly posting their prices (which I think are priced well enough to be considered wholesale but I’m no seafood expert).
