When it comes down to striptease clubs they do have some unique stuff in Porto. It might be nothing crazy and wild like in Central and Eastern Europe but very worth checking out. The Lingerie Restaurant chain (https://porto.thelingerierestaurant.com/) is a cool and original venue. It’s a franchise of restaurants where you get served by half-naked waitresses and waiters. There’s a pole between the tables for the occasional dancer to show up while you’re eating your steak.
There is no shortage of standard gentlemen’s clubs either. Try Mask (https://maskporto.com/) at Av. Fontes Pereira De Melo, 449/457 if you tend to wear a suit or Life Club (https://www.life-club.com/) at Rua Conde Vizela 100 if you would prefer a more informal atmosphere.
