The most highly recommended steak is at Shulas (DDP not accepted). If it has to be DDP there are good reports about the steak at Flying Fish although they offer only one steak. I don't know about Yachtsman. I have a friend who didn't think their meat was worth it.
I agree with your friend. I've had several of the steaks at Yachtsman and haven't been impressed with any of them (NY Strip, Porter House, or Filet). Now if I go with someone who wants to eat there, I get their lamb. (It is very good.) I like the seafood salad as an appetizer, but have yet to find any of their desserts that I care for.
On the other hand, I love all three courses at Flying Fish (tomato mozzarella salad or mussels for appetizers, steak for entree, and then a cheese plate or whichever dessert trio they are serving that night). They only have a char crusted steak on the menu, but it is better than any steak I've ever had at any of the other Signatures (Yachtsman, Artist Point, Citricos, Narcoosee, Artist Point, or Jiko).
For one credit we've gotten good steaks at Coral Reef of all places, Mama Melrose, Rose & Crown, Chef's de France, and Turf Club. I used to like the filet at Le Cellier, but the last few times we've dined there the food has been too salty to even eat. Le Cellier is one credit at lunch, but two credits at dinner.
For a counter service credit you can get a Mexican steak over at the CSR food court (Pepper Market). It's just OK though. It comes with black beans, rice, and a side of guacamole, jalapenos, and pica de gallo. It's more of a skirt steak, like you find in fajitos though. For a CS credit it's not bad (and they have really good chicken nachos over there if someone else wants nachos).
