Narcoossee's has many staunch supporters, but for me it has always been underwhelming. Is it good? Yes. Is it spectacular? No. Service has been spotty, good or bad on various nights, and the food while certainly satisfying is not what I would deem highly creative or interesting. And, naturally, given the type of things they serve (lobster, for example) it is quite expensive. So overall, I have been less than thrilled with my experiences there. Not unhappy, but not thrilled.
Artist Point, on the other hand, is one of my and several of my travelmates' perennial favorites. I find their fare much more appealing from a point of nuance and detail. I have never, in two dozen or so visits, had anything but good (and often stellar) service. I also like the decor and find the resort (WL) a lovely and peaceful place to spend an evening.
