O Prego da Peixaria

it's a cool, modern, unique restaurant that looks really stylish and original, you can share a table with other people and the menu is also very particular. it's a "hamburgueria" but you don't eat just usual hamburgers, there are all kinds of burgers, fish burgers are the speciality of the house. (I had a salmon burger with brown bread and it was so delicious!) It's not too expensive for Lisbon and the quality of the food is really high. You can find all kind of spices and sauces on the table that you share with friends or strangers. There's a good atmosphere and I definitely recommend it.
