I just remembered that BCD said one day at lunch a party of two wandered into Le Muse. They were looking around for a table when Mehmet (maitre' d) spoke to them quickly and then escorted them out. I totally missed this -- that's how quick it was.
On Divina, we do frequently see people in the hallway outside of the entrance to Le Muse stop for a moment maybe thinking, "Hmm, what's this restaurant?" Then they see the YC signs and realize that it's not for them. The restaurant is near the adult pool restrooms, so it gets attention when people come inside. First time we ever saw someone try to enter though.
