You have to eat a “Bifana” if you come to Lisbon. You must ! It’s part of the experience of visiting the city.
It is true that I could bet that every single person that visited Lisbon has eaten, tasted or spotted this Portuguese beloved “dish”. Many “cafés” serve this kind of sandwich consisting of a thin slice of pork beef slowly cooked in a sauce of white wine, garlic, laurel, butter and red pepper powder (paprika) and many of these places actually have a store window for you to watch them cooking it.
You can add mustard for the traditional flavor or any other sauce you like; or just taste it simple to appreciate the real tasty flavor; you should pair the Bifana with an “imperial” – a chilled 25cl glass of pressure beer. And it’s an incredible cheap snack!
Although I’m pointing out this spot, there are many others serving this dish all over Lisbon. However this particular one is chosen by many as the best spot. And you should forget about going to a fancy restaurant; this, like many other spots serving Bifanas, is just a little shop with a balcony and no tables.
The point is, the taste of this sandwich is worth looking for it!
