I've posted about these guys before. Frankly, I think we're blessed to have a fish monger of this quality nearby. Hell, I don't think there is a better spot in the Mon/OC for seafood, or even the State.
Last week, however, I sent my Dad over the Bridge to get what he thought looked best. The guys sent him back with a chunka tuna for me that they swore by. I was gonna freeze it since I had already prepped so much food, but then I tasted a little slice. Wow! I mean, really, Wow! I wound up serving a few thin, raw slices with just a coupla drops of soy sauce on 'em. It totally upstaged the scallops my buddy brought me from his boat (and that I cleaned myself after only a short time outta the water).
To be clear, I owe these guys nothin', but, as a loyal 'hound, I feel it worth given them their own thread. In season, their fluke is a big favorite for us. My only suggestion is that you go in and be frank about what you want - "Hey Man, I'm a dirty food dork and I don't care much what I get, just tell me what you'd eat tonight if you were me?"
