As the saying goes, you've had the rest, now try the best. The rest in this case is unsubtle glop: white starchy glop that tastes more like bacon and potato than seafood if it's something like New England-style clam chowder; red starchy glop that tastes more like chili powder and tomato than seafood if it's something like Manhattan clam or Caribbean conch chowder. So now try the best, which you'll no doubt be able to do for a good many years, since Norman Van Aken's regulars would probably kill the chef if he discontinued his conch chowder. Slight variations have occurred over the years (like the current cloud of foam on top), but forever ambrosial is and will be the inventive chowder: panko-crusted pieces of tender conch plus garnishes of citrus, shaved coconut, and a few vegetables floating on a slightly hot, slightly sweet, rich yet refreshingly reduced (not starch-thickened) shellfish stock flavored with saffron, star anise, Scotch bonnet peppers, orange juice, coconut milk, and a generous dollop of cream. The rest simply can't compare.
