Where to get the best Chicharones in Chicago?

We are up on the north side and are still fairly new to Chicago. This place by us, Edgewater Produce seems to have a pretty decent hot case with Chicharone and Carnitas.

Which led me to wonder - where can I pick up the best Chicharone around (buying in quantity, for a party, so a take out order of Chicharon is not what I am thinking)? I imagine Pilsen or some hidden South Side store is the answer.

Before I go wondering through these foreign lands I thought I would check in and see if there were any recommendations
