Seafood is as much of a staple on Miami menus as are kitschy takes on the Cuban sandwich. But like with so many things in life, the ones who do it simplest, do it best. Case in point: Danny Serfer’s Edgewater restaurant Mignonette, where the menu starts off with the best selection of fresh oysters in Miami, then graduates onto a lobster heavy-list of appetizers highlighted by the croissants with lobster butter. The “plain” entrees are the way to go here, where Serfer lets the selection of local fish speak for itself. But if you insist on exploring the fancy stuff, the swordfish with duck confit is your best bet.
