Rua Maria Quinteria contained many of the restaurants I bookmarked to checkout during my stay in…read moreRio. Maria e o Boi received a Bib Gourmand rating for its Brazilian cuisine and I was definitely pleased with my experience over dinner. It was located on a corner lot with a couple tables outdoors, 8 tables inside with a large, well stocked bar. I thought the decor was inviting, simple and good for lingering over a long meal and conversation. Printed menus were only in Portuguese but the clipboard had a QR code to link you to the English version. The restaurant was known for their meat dishes but I veered to the Pirarucu, white fleshed Brazilian fish, as it was the only place on my list with it. It turned out to be the best fish I ate on this trip. The Pirarucu was firm but moist and complemented with the ajoblanco sauce (almonds, garlic and bread), a "scented chimichurri", Brazil nut like side (per menu but they looked and tasted like beans with tomatoes and green grapes) and kale. It was a delicious mouthful when I could get a little bit of everything onto my fork. I added a side of grilled vegetables (zucchini, kambocha squash, peas, and broccoli) which all were nicely charred and tender. It was a little bit over-seasoned with salt but still good. Service was as expected. A 10% service was automatically added to the bill which was settled at the table. Would return for another meal when I'm back in Rio.
