Memmo Alfama Terrace, Lisboa -This bar is on the first floor and not on the rooftop of the building of the Memmo Alfama Hotel, but it is at the top of an entire neighborhood -- picturesque Alfama. It has some of the best views of the Tagus and of Lisbon’s oldest district, and a contemporary décor. It’s by the hotel’s outdoor pool, offering a selection of Portuguese wines and tapas, to be enjoyed along with the magnificent views. It opens every day, from 6PM to 11PM.
Sky Bar, Lisboa - Found at the top of the Tivoli Hotel, this is a lounge area with sofas where you may gaze out to the river, to the castle and downtown. It offers a good list of cocktails (including non-alcoholic) and there is also a choice of snacks. It opens late in the afternoon, but only in the warmer months, usually between May and September.
Rooftop Bar, Lisboa -Be blown away by the view from this terrace on the 9th floor of Mundial Hotel. The castle is so close you can almost touch it, and you can see almost all of downtown and Chiado. It opens for pre-dinner drinks but also invites you to end the night with a cocktail to the sound of jazz.
