If your Portuguese language skills are limited but you want to eat like a local, throw caution to the wind and try Casa dos Passarinhos. We left the decisions to our server (who spoke no English) and we weren't exactly sure what we were going to be served. My grilled mackerel ... correction ... two whole mackerels were delicious, and the assortment of winter vegetables was tasty. My husband ordered the pork special. He was served a huge platter of assorted pork and sausage pieces along with veggies and rice. (It seems we frequently are served at least two starches at dinner here: rice and potatoes.) The house wine was wonderful (less than 4 euros for a large carafe). Despite eye-popping portions, we managed to have dessert too. The restaurant offers a nice assortment of custards and some tarts/cakes. The ambiance is lovely too. Our total bill for one of the most extravagant dinners we've had in Lisboa was around 35 euros.
