In São Paulo, Brazil, Modern Mamma Osteria is best approached as an Italian restaurant: specific enough to guide expectations before you book. The draw is ingredient-led cooking, comfort and a clear sense of place; at a polished mid-to-high price point, it should be judged as a polished dinner worth planning ahead for. It is most compelling for diners seeking a full, chef-led dining experience, especially if the night calls for something more considered than a safe default.
