Sorry to hear of your poor experiences. We recently returned from a 10 day trip. We stayed on the French side but ate at many locations on both sides. Other than mediocre food and service at Layla's (but acceptable, still enjoyed ourselves), we all commented how good the food and service was everywhere (including a great time at Buccaneer with nice live music). I don't expect that everyone will always bring their "A" game, but this year was consistently excellent for us.
