I never hear people talking about this, though I mentioned it in my book. cono's, in williamsburg, is a good neapolitan fish restaurant, very old fashioned (so old fashioned that you can't easily find this style of cooking in naples anymore!). I recommend it.
but there's a takeout window at the rear selling INCREDIBLE hot heros. Really wonderful. And you can watch the action in their amazing, bustling, gleaming kitchen while you wait (pick up cooking tricks!)
