I had originally driven past here when leaving the nearby mall a few days prior. It looked nice,…read morehas its own dedicated parking lot, and wasn't packed.
The evening I decided to go, I arrived on a weeknight at about 6PM. We were the only people in the restaurant, and they almost appeared to not be open yet, but they welcomed us in and sat us.
Because we were early, not all of the self-serve bar/salad bar items were out yet, but they were populating it as we were there so it wasn't an issue. They were very accommodating with bringing out meat just for us even though we were the only ones in this restaurant at the moment.
By the time we left, a few couples had come in and been sat, but even at 7PM it was still not busy. All in all though, it was an excellent experience with excellent food and I wouldn't hesitate to come here again if I was in Guarulhos again.
(It was my first time having duck hearts too! They weren't bad, but it isn't really a food I'd ever get excited over).
