The location of this restaurant in a private scientific foundation on a curve of the river just before it meets the ocean is enough to take your breath away. Add to that the landmark building and the restaurant's dramatic interior, and dining here is a real occasion. The food is inevitably hard pressed to match the setting, but is good and pretty well priced, with a range of pasta and risotto dishes as well as more elaborate bacalhau and meat dishes, plus an excellent wine list. You can also enjoy tea or a drink on the café terrace.
