Since RM Seafood opened on Valentine’s Day, 2005, Rick Moonen has set a new standard for seafood in Las Vegas. Located at the mouth of Mandalay Bay, an upstairs dining room with a yacht-club feel attracts a mix of high rollers and locals. Playful touches include portholes that peek down on tanks of live crustaceans. A champion of sustainability, Moonen simply prepares seasonal sea life to preserve their natural advantages. Beverage Director Jeff Eichelberger is similarly intent on maintaining the earth’s bounty for perpetuity, favoring organic, biodynamic wines. Top desserts utilize fresh fruit in tarts and ice cream.
