Recommendations in Lisbon and Porto?

Hi there,

My wife and I took a really last minute trip to Portugal and love it so far. We usually plan much more in advance but the opportunity snuck up on us and we decided to just check out Portugal on short notice.

Any recommendations for: Scenic views Excellent coffee (especially cold brews) Seafood (or any good food really, preferably not too expensive) Books/literature Fado music Cultural events/concerts, etc.

Thanks in advance! We are currently in Lisbon but will check out Porto in a couple of days.
