Just recently went to Bufete Fase because one of my friends who lives there told me that's where I would find the best francesinha. It was to die for. Very long line so if you don't mind the wait you definitely have to try this place. I have tried a few other places but this one was my favorite. I am recommending it to everyone. I've heard that Santa Catarina has a few good places. Maybe I will try in that area next time.
