Food varies greatly, so always make sure your char should be eating it. IE. Mr. Corrlaan Pally probably shouldn't be eating steaks made from Relagar the elf, or the Limb Snacks from Udgaard (I love these).

Also, theres almost always a least one food item found in the various taverns, which can be pretty good, so don't discount those.

Also a big newbie mistake is buying 40 deep fried turkeys because they're cheap and effective. Weight matters!
