The two "main" restaurants at WL are Artist Point and Whispering Canyon Cafe. Both get great reviews, but have very different atmospheres. Artist Point is a more "adult-like" setting for more of a fancy sit-down meal...steaks, salmon etc. WCC's food and atmosphere is more casual...meatloaf, ribs, chicken, corn on the cob, beans. There's also a lot of entertaining going on while you eat and a lot of interaction.
By the way, if you're on the dining plan, AP is 2 TS credits per person, and WC is 1.
