WoWWiki has a nice chart showing all the foods available that give you a "well fed" buff:

The chart shows food organized by level requirement, with columns for each buff it gives you. Consult this chart when shopping for food that gives you the best benefit for your class and level.

Our guild has multiple chefs able to cook almost every recipe in the game, so be sure to ask in guild chat if you need a particular recipe cooked. You can get a rough idea of who can do what by looking at the guild professions page.
