When I lived there, I used to love to eat at B.B. King’s on Beale St. Good food and good blues. There was also a good Mexican chain there called El Porton. It may not be open anymore. Also, for good ribs that aren’t overpriced like the Rendezvous, try Jack’s Rib Shack. They might not be open anymore either. Good bars with bands: Stage Stop (hard rock), Shooters and Neon Moon (country club). Those places may not be open anymore—I lived there in the early 90s. The zoo is outstanding. Definately check out the Peabody Hotel for the ducks and cocktails.
I'd recommend The civil rights museum, Graceland, the Memphis Zoo (polar bears are so cool!), Gibson Guitar museum, Sun Studios, Tunica (ok...so that's in MS! LOL)
Above all...be careful. We have lots of killin' and shootin' and carjackin' and robbin'...
