Marco is a great restaurant, centrally located and reasonably priced. If you want to try one of the flavors of Porto in Lisbon, this is one of the restaurants to visit. Great Service. Keep in mind that a full plate of Francesinhas a large plate, so always Posh a mini plate if you don’t eat much. Great group menu prices including drinks. Great and inexpensive Portuguese wine is also served and the service is friendly and attentive. Must try their Francesinha specialty, “Little Francisca,” which is not small at all! They don’t make reservations, and it is very busy at lunchtime. You may have to wait for a table, but it’s worth it.
