I´m not easily surprised by eateries, but Madre Terra - an Argentine-run artesan kitchen and bar - is right up there with the best of them.
Midway along Rua Manuel de Carvalho - the road that links the Rio bus terminus with the heart of Centro in Buzios - the restaurant (it translates as Mother Earth) is modest from the outside, and modest enough inside too.
But it is based around some of the freshest, best-prepared and most inventive light dishes, and it gave us a truly memorable meal to take on a four-hour coach journey, beautifully packed and ready to eat.
I think we were the envy of everyone else on that bus ride as we unpacked not just the sandwich that we´d each ordered, but also an unexpected side order of sauteed potato which also came in the foil container.
Madre Terra is a family-run bar and artesan restaurant, opened in October 2016 and operated by true food enthusiasts and perfectionists.
The prices are absurdly cheap (under 20 reals for a very satisfying meal) and freshly made, the ingredients are first-rate, the care lavished on the preparation shames many rival establishments, and everything is done with humour and friendliness.
It´s compact. Smart, simple black seats around the handful of tables inside the light and airy interior (cooled by rotating wall fans), extra streetside tables for eating out, and scrupulously clean loos.
Behind the counter, the two staff chop, cook, mix and serve.
It´s vegetarian-friendly, though it´s by no means exclusively veggie.
My companion had an aubergine, cheese, mayo and tomato filling in a multi-grained bread, while I went for ciabatta (warmed and lightly grilled) and filled with gorgonzola, broccoli and caramelised onion.
Each, as I say, came with a side order of sauteed potato.
Had we not been leaving Bouzios that day, we´d have almost certainly ventured to this wonderful gem of a light restaurant again. A great find.
