The aptly named Atlantis looks as though it's risen from the waves and clamped itself to the cliffside above the suntrap beach below the Galomar Hotel. Seating options are on chunky wicker inside, or out on the terrace above the crashing Atlantic. You'd expect an exclusively seafood menu, but meat and even uncommon dishes like duck make an appearance.
For dessert, go local with the Madeiran blueberry cold pudding. No swimsuits allowed after 7pm.
