My spouse and I dined at Restaurante a Mineira on Avenida Quintino Bocaiva in Sao Francisco, Niteroi, for lunch with our tour guide in February 2012. The restaurant offers an extensive, authentic buffet of hot and cold Brazilian foods that we very much enjoyed. The restaurant was uncrowded in the late afternoon (however, the patrons that we saw were locals, not tourists), but the foods were kept tidy and replenished. Lunch for three people cost approximately $40, including drinks (mostly non-alcoholic) and gratuity.
