Estoril Casino
Thought to have inspired the James Bond novel (and subsequent movie) Casino Royale, the glitzy Estoril Casino retains a glamorous allure. It's one of the largest casinos in Europe, with a nightclub, art gallery, bars, and restaurants alongside the gambling salons. You can make an evening of it here, with dinner and dancing to live music or DJs, but it's a pricey night out.
