I thought that enjoying quality wine with elegant ambience and adult crowd in Barra da Tijuca…read moresounded idiosyncratic. But then there's Grand Cru. Hidden below a residential building, you will not believe there's anything happening there. You can't even hear a sound from the outside. And then you get in and it's like you are entering this magic cave with hidden treasures. You see all many bottles of wine. Your hear voices. The lighting invites you in. And then there's Sandro with his friendly smile and help picking just the right concoction for your palate. Yes, outside is "Rio 40 graus" but inside a new world is opened where you can drink red wine, listen to amazing live bossa nova, watch animated Brazilians having fun and get lost. Lost and found.
