Review for Costa Cruises - Costa Classica Review For Piazza Navona Grand Bar Google User Jun 17 '18 at 6:10 Fabulous Hotel, but EXTREMELY CONCERNED that their concierge is referring guests to restaurant Rinaldi al Quirinale. Look at reviews and several sites state referred by my hotel and several stated St Regis referred them! Follow up on where concierge sends you- may be getting a kick-back. The restaurant is a SCAM, tourist trap... reviews all say same thing. Hotels need to know this and quit referring RINALDI AL QUIRINALE! View full site to comment or like
