One Piece volume 6 features story and art by Eiichiro Oda.

Luffy and his Straw Hat Pirates thought they were just stopping in for a quick bite... but now Luffy's been made a busboy on Baratie, the Oceangoing Restaurant, and it turns out some of the worst-mannered pirates on the Grand Line are just dying for a meal. Always one to look on the bright side, Luffy sets his sights on Sanji, the smart-talking, skirt-chasing Maitre'd of the Baratie.

But Sanji doesn't want to go, and it just may take a battle between the two most dread pirate crews (not to mention a little sweet talking from Nami) to convince him to join the Straw Hats and uphold his oath to feed any and all pirates in need. The question is: what do you do when the very same pirates you just fed now want to serve you up for dinner?
