Fish / seafood markets near Chinatown?

I was hoping to swing by a good fish market on my way home and Chinatown is on the way, so I thought there might be a LTH-recommended seafood market there. Isaacson & Stein closes pretty early (4:15) so it's not really an option for post-work shopping. Are there good markets near/around Chinatown or environs with a nice fish selection? I was hoping to avoid the parking debacle that is Whole Foods.
