The seafood in Lisbon is incredible and a must have anyplace you go. Located in the center of the city is a cute restaurant called Fidalgo that had been recommended by a local. It is a traditional Portuguese restaurant and they have a variety of options to choose from.
I definitely recommend the octopus that comes with a hot garlic and oil sauce to pour over the fish for extra flavor. The potatoes were also to die for and melted in your mouth at the first bite.
The restaurant is also covered with hundreds of different wine bottles so you will be sure not to leave thirsty.
