Apples and Oranges...
Well, I voted for Fulton's, but that is the obvious choice. You are looking at $75 a head there though. You might be able to get out of there for about $50, but no less.
Pecos Bill is a counter service restaurant, ok food, but you get what you pay for.
ESPN Club is fun, especially if there at night. Food is pretty good, great atmosphere if you like sports. $15 per person would do it.
Hollywood and Vine isn't my favorite restaurant, but it's not bad. Price varies upon time of day.
Brown Derby is a replica of the original Brown Derby, and the food is pretty good there. I really have enjoyed eating there. It is a quiet refuge from the MGM noise. I think our meal was $60 for four of us for lunch.
Liberty Tree is a fun place. They have great pot roast and other 18th century favorites. Good place to relax from the long day at Magic Kingdom. Dinner is about $20 per person.
Overall, there are far better restaurants that those you mentioned. Any of the deluxe hotels feature wonderful restaurants. Artist's Point, Spoodles, Flying Fish and Jiko are some of my favorites. Spoodles is reletively inexpensive, has a great variety of food and is in a convenient location. I never miss it. Oh, and don't miss Kona Cafe in the Polynesian. It is the best breakfast around.
