Imo, Naoise's rapture moment is an excellent spot of bliss without sex though, and the hidden highlight of the brothel.
Have you seen Naoise's scene if you have control of Minsc when you talk to her? It's hilarious. I detest a lot of the brothel content, but I like Naoise's scene, I love the cat, and I have a soft spot for Sauceman Chorizo. Poor guy just wants to cook without being propositioned by confused patrons.
As much as I don't like Gale's scene with the twins, I do like the dialogue you can have about the whole situation with him now that the player dialogue has been modified. It helps to put some things into perspective and makes me appreciate him even more - especially if you chose the none-astral variation in act 2.
