That's where we stayed. Great place.I was told that if a seas bass is for sharing it means it was caught in the wild as the sea farmed ones aren't allowed to grow that big.
I had some great fish meals in Cascais which is basically a suburb of Lisbon a couple of years ago.
There was a restaurant there that I heard a local shop keeper recommend to some tourists. Been around for 40 or 50 years. Fish restaurant. Proper old school. Old men waiters in white shirts and waistcoats.
Shared some mussels, then had hake and my wife had amazing swordfish. Lovely bottle of Portuguese white wine. Rounded off with a glass of their oldest port.
I ate some really good food last week.
