We will be in Porto for a short break in late November and are thinking about some of the following restaurants: Bull & Bear; Marisqueira Mauritania; Mariazinha; Rosinha. We are stayin in Foz, so we are thinking that the restaurants in Matosinhos will work well for us. We are looking for very good regional food based on quality local ingredients from a kitchen that cares about its quality. We are not fussy about expenses, but we would like to avoid ostentatious or pretentious places. We would very much appreciate any thoughts or advice for us. Thank you.
