I picked Citricos because we have never had a bad experience there. It does not offer a view so it makes itself special thru service and quality meals. Nice wine list too. Artist Pointe would be my second choice. Superior service and good meals. Later dining time almost ensures a quiet room. Jiko is also a good choice (my 3rd), excellent wine list and usually quiet, some people fear a too exotic menu and typically families might shy away from it. Food is excellent and not that "exotic". After dinner a stoll around the hotel is very nice.
Narcossees has good food but I have never had a quiet/romantic meal there, pretty much the same for California grille (which in my opinion is losing its grip on service.Probably because of the fireworks view. Yachtsman and Shulas are good but I don't think them to be special.
Each would be a fine choice for a dinner, but I would pick Citricos for special occasion.
