Bistrô do Paço
Facing the patio at the cool, whitewashed Paço Imperial (The Imperial Palace) and close to the Palacio Tirandentes in the Praça XV square, this charming little bistro is a good option for a light lunch, coffee, or snack for Centro sightseers. European influences abound, and the vegetarian-friendly menu includes salads, quiches, and grilled fish; make sure to leave room for the tempting desserts.
