This a small "hole in the wall" restaurant, that we'll blow your food receptors away. It looks like any small restaurant in Lisboa, but those ribs... AMAZING. The people working there know only portugese, but they call the ribs "piano", so you just need to say the magic word. I highly recommend going there hungry and getting a "piano" or two :) On top of this, it's cheap. The only reason I don't rate it "Excellent" is that it's a little small - it has 5-6 tables inside in total. Nevertheless, I visit it every time I go to Lisboa.
