Seriously, if you're going cannibal, you need to go for the ulitimate perk the Meat of Champions

I haven't been able to eat The King yet though because I like him, but one of these days!
Also, make sure to stop by Sloan and talk to the chic inside the shack, Jas, it's a riot when you get to reply using the cannibal perk! Also make sure to do the Beyond the Beef for the White Glove Society as a cannibal, it's better to go there if you are unknown, you'll get better dialogue and you can use the cannibal perk right away, especially if you are working for Caesar, he gives you the quest, go as an unknown to the strip and inititate with the cannibal perk, you'll be glad you did, it's very funny!
btw, I voted other on your poll so I could explain the cannibal stuff to you in case you didn't know.
