GREAT Brazilian Food, well presented, nice waiters and the best is that it is inside an Art Gallery, that hosts lots of good expos in town.
You pay a fixed price (week days are the cheaper, and sunday the most expensive). But for the quality, and as it´s all included (food and desert), it´s not all that bad at the end.
My tip is for you to arrive early, there´s always a line!! When we went there, we arrived early, saw the expositions and got in by the time it opened.
It´s a MUST GO!
