A genuine Bistrô experience in Rio, the menu at 66 features the kind of french staples worthy of the title - Aunt Madeleine's steak tartar and the moules marinière to name but two - and a variety of good pasta dishes. Another of Michelin Star magnet Claude Troisgros' establishments but this time a little more affordable and keeping things rather more simple than he does at Olympe, plus 66 does a good value lunch and three course dinner menu.
