Dom Mário is hands down the best restaurant on Ilha Grande in Abraão!
Make a reservation if you're coming with a large group or on the island during the busy season or holiday week, as they don't have all that many tables.
You start off with a bread basket and homemade butter with herbs and they had lots of English music playing on the speakers throughout the night. That butter though.
Try at least one of the many caipirinha or caipiroska varieties for 12-14 reais each. I tried the maracuja com gengibre (passion fruit/ginger) and maracuja com manjericão (passion fruit/basil) and loved both of them. If you're a foreigner ie non-Brazilian, let them know if you prefer more or less cachaça in your caipirinha to get the drink of your taste.
Vegetarian dishes are very sparse here, though my waitress did mention they had a veggie risotto that wasn't on the menu and they may have others as well. They are mostly known for their seafood dishes. I enjoyed my filet with gorgonzola sauce too.
The restaurant is al fresco with a covered roof. Some of the tables are in the sand, so you can feel like you're on the beach even though you're a few steps away from the sounds of the waves crashing in. All around, a great experience and not so in your face of a tourist trap like the beachfront restaurants. read more
