South America style meats in DFW area?

[HyperSpanner]

Does anyone know where I can find good authentic linguica in the DFW area? I'm looking maybe a South American style butcher shop or grocery store where I can get Brazilian cuts of meat like picanha. A place that makes their own sausage would be a super plus.

I just don't want to have to pay $7.99 for an 8oz package of bland, mass produced crud at wholefoods.
