Bairro alto is a street full of bars and small club , you have also the neighborhood Cais do sobre, with the same vibe !
You have also lots of roof top bar to have some for drinks :
- Silk club: Japanese restaurant/bar/club! Quite expensive but amazing view of Lisbon by night
- Lost in esplanada: Super good Indian atmosphere restaurant/bar (best is early afternoon)
- Skybar, quite posh, on the roof of the Tivoli hotel, lounge music, catering
- Park Lisboa, the simplest of all, nice for a good beer, view of the big bridge of April 25 which crosses the Tege
For the nightclub for me the best is by far lux fragil , not easy to get in , so come early ( the entrance price vary from 10-20€ ) but it they don’t want you in , they will ask you 270€ each to get in !
Go dress in black and keep quiet in the queue is the best advice
Then you have also nice after party starting early morning …
Lisbonne is a really nice city , i have been going there for the last 15 years at least and still living it
Have a great time
