i can't decide on one of those restaurants.
Both Narcoossee's and the California Grill have what I'd consider very similar Filet Mignon options. I'd suggest leaning towards the California Grill (because of it's spectacular view, and their fabulous flatbread options), but though that would just make it more difficult for me to eat there. So, yeah. Narcoosee's! Seriously. Both options are great. (go to Narcoosee's, avoid the California Grill on the days I want to go)
Also, the California Grill currently does have some interesting options along with their filet; Wagyu Beef and Bison Strip. Narcoosee's is just Filet. (as of two days ago)
If you have to drag some non-steak lovers (is there such a thing?) with you, I've recently had Narcoossee's Pork Chop (so huge I'm still digesting it) and Halibut. Both were spectacular.
My favorite steak-experience is at Jiko's. Though they only offer Filet. Everything is influenced by African cuisine. I believe the Filet has a rub on it that really enhances the flavor. It sits on Spoon Bread (corn soufflé?) and a delicious, dark red wine sauce. I've actually eaten this twice in the last few weeks. It is to die (well, the cow at least) for. (no offense to cows)
I can't say for certain, but I wouldn't be surprised if Jiko's used Sous Vide for their Filet. While it is definitely finished on an Oak Grill; their Filet has the most consistent top to bottom medium rare doneness (?) I've ever experienced. Sous Vide may be two 4 letter words to a chef, but if it gets the job (medium-rare) done, I'll take it every time.
The other draw (at least for me) at Jiko's is the Taste of Africa appetizer. Four different dips served with Lavash and Naan bread. You'll either find this an amazingly delicious dish, or a strong not. Again, Jiko's African influence makes for a very different dinning experience. So, it may not be for everyone.
If you are a big wine(-o), you should know that the entire wine list at Jiko's is from South Africa. That could be a deal breaker, if you actually pause between bites to have something other than steak. (as if)
Not to leave out the Yatchman's Steak House. Again, another signature (Disney's term) restaurant. Lot's of aged beef. All very good. If you have a Thurston Howell III outfit, you're experience will be thematically perfect.
Le Cellier has been raved about for a long time. So when I finally tried it, well let's just say my expectations were Soarn'. (wow, I crack mysef up) It was fine. No complaints. Probably just an expectation thing for me. So ignore my comments. Maybe I didn't care for the basement ambiance.
My ranting and ratings:
1. Jiko's (perfect filet and Taste of Africa)
2. California Grill (the view and flatbread)
3. Narcoossee's (cause I don't want you going to #2)
4. Yatchman's Steakhouse (you won't be disappointed)
5. Le Cellier (yawn, I mean awesome!)
6. Go to all of them. (duh)
