The main city bar scene is down at Ribeira or across the river in Gaia – at the latter, in particular, you can hop from lounge bar to dance club in the Cais de Gaia development at the far end, where soaring glass walls, infinity pools, fountains and roof terraces vie for the punters’ attention.
There are more bars out to the west in Massarelos (particularly the floating pontoon bars of Rua do Ouro) and in beachside Foz do Douro, while most of Porto’s favoured clubs tend to be around Boavista, in suburban Ramalde near NorteShopping, and way out in Matosinhos. For port wine tasting in refined surroundings there are two main bars, the official Solar do Vinho do Porto (city centre) and the Vinologia wine bar (Ribeira), both excellent in their own way.
Most bars don’t open until 10pm and stay open until 2am, later at weekends (often until 4am); exceptions are noted below. Clubs open (or really only get going) at midnight, and most stay open until 4 or 5am or later, with a standard e5–15 admission fee, more for special events and top guest DJs. The entrance ticket acts as a voucher for free drinks, not that it’ll last long as prices are pretty high.
