I used to absolutely love the Yacht Club. I loved it so much. I never got off the dance floor. It didn't matter if I was dancing with some rich guy coming off a yacht, or the guy who washed the dishes at the restaurant I was at that night. It was open to all and it was so much fun. And sometimes I just danced alone on the dance floor. It was hot and sweaty and smokey. Sure, there was some pressure to get bottle service, but it didn't matter if you didn't. I remember leaving at closing time disgustingly sweaty and smelling of smoke (I don't smoke) but it didn't matter.
My little foray to Bagatelle on Saturday night (because my compatriots wanted to go) wasn't nearly as much fun. First, yes, I'm older. But also, the music is awful, thump thump thump. Plus, it's filled with that self importance of "look at me, I just spent $1000 for champagne," with that contrived pomp of the delivery of the bottle. It's forced gaiety, not real joyful abandon, like even the old Le Ti was.
But you can happily spend a vacation on St B without any of it. That's a bummer to stay at Le Toiny, that oasis of elegance and have to deal with the banging sound of electronic music, but otherwise, it's easy to avoid it and just enjoy all of the other things the island has to offer. You don't even need to go to any of the St Tropez type restaurants, there's enough other ones to enjoy.
