I went to porkys for years. Its pretty far from the airport, is packed jammed at peak hours and is pretty much a dump. Its open 24hrs though, which is cool. BTW, referring to the one on 56th, the one in the Hammocks is much nicer, but way farther sw.
I just remembered "The Muscle Factory'" Its off of sw 40th and the palmetto. Its back by the warehouses. Its not pretty, but is hardcore.
