It's located in Rua Costa do Castelo 1, by the castle, and from there the river Tejo feels like a frame of Praça do Comércio, with the Bridge 25 of April and the Cristo-Rei statue as its limits.
During weekends or holidays, you can just walk in, enjoy the view, and drink a bier (food could be beter...). During the week since students are having classes, you can take a quick pick but if you want to calmly enjoy the view, I recommend the restaurant on the first floor. After 7pm the Bar and the Café are open without restrictions! And in the basement there's even a Jazz Café with live music!
