Food: Taberna menu with several fresh, simple and very good staples, plus daily specials. I love it every time.
Wine: Try the house wines, which are local from near Tomar. Plus beer on tap.
My take: Highly recommended. Go to Tomar. It was wonderful. The magnificent Convento do Cristo 12th C Knights Templar/Order of Christ fortress there blew my mind. Casa Matreno and Casa das Ratas are the same owner/kitchen and just across the street from one another. The sidewalk seating is lovely. More on Casa Matreno. More on Convento do Cristo.
