Since this gets asked alot, I have tried to compile a list (with the help of The Knot and Wedding Wire) of DFW venues that allow outside catering. Please keep in mind that it may contain some errors, is not exhaustive, and that some venues may only allow outside catering from a preferred vendor and/or additional fees may apply. Knotties feel free to add your venue to this list. HTH.
