First and foremost, castle place is massive. It's easy to see why it is one of the most popular…read morebeach clubs in Nice. The food, in general, was delicious. I actually think the straciatella was one of the best things I've ever tasted. That and the halloumi, as well as the ceviche, were our favorite items. The octopus, both in the fritto misto and the grilled octopus, was unfortunately rubbery. Overall, I would definitely recommend Castel Plage for a lunch or dinner.
However, I had to dock a few stars for the service quality at the beach club itself. I understand that the venue is large and busy, but there's really no excuse for how inattentive the staff were. We were sat and told to peruse the menu, then didn't see our attendant at all. After about an hour and half later, and multiple unsuccessful attempts to catch the eye of our attendant, another group pointed their attendant in our direction so we could finally order just some water and drinks.
Overall, I would highly recommend the food at Castel Plage, but I would suggest looking elsewhere on the beach for a true luxurious beach club experience.
