BBQ Joints and Blues Clubs in Jackson Mississippi?

I haven't been in Jackson in over 30 years so I can't help you with much, but a while back on TV there was a mini blurb about The Big Apple Inn and their famous pig ear sandwich. Walking distance from downtown.
I think they should be helpful for blues joints also.

The best BBQ I have found locally is Cassatta's Meat Market and BBQ in Flowood (Very short trip), but they are not open late or Sunday's, so plan accordingly. After that, it is, IMO a good sized drop off.. I do recommend Fannin Market, (which conveniently enough, is located next door to Cassata's,) for some pretty good country style offerings, they are open for lunch, and Thursday and Friday nights...

I also will throw this out, I personally would no go anywhere around the convention center area on foot, despite what they say. And I am not a cautious type...
