CASINO KURSAAL. Play & Fun. Place your bets! The roulette wheels at the Kursaal Casino haven't stopped turning for centuries. Situated in Calle Mayor (the High Street), in the heart of the Old Part, the Casino, which is an institution in its own right in the world of betting, also has a restaurant, “La Boule”, and an exhibition hall which, when the sun goes down, turns into a party room brimming with ambience.
