I would recommend going to the Anaheim Gardenwalk, there are a lot of really good choices that you can check out and decide where you want to go based on whatever you're in the mood for. Personally my favorite is FiRE+iCE, its a grill where you can pick all of your own ingredients to make your own meal and they grill it right in front of you! Not to mention its all-you-can-eat style always leaves me super full and satisfied.
