La Bêtise is described across reviews as a warm, cozy, and welcoming spot with attentive staff and a lively yet intimate ambiance. The menu gets strong praise for fresh seafood and innovative tapas, with oysters, scallops, tartares, octopus and fried cauliflower among the standouts, and generous portions in tapas style dishes paired with a solid wine and cocktail selection. The décor and terrace add to the charm, making it a good setting for dates or casual nights with friends. Service is repeatedly noted as friendly and helpful, though a few comments point to occasional delays and some items priced on the higher side. Taken together, the experiences point to a memorable dining destination that many reviewers would happily return to.View restaurant profile
