What restaurant did Sanji work at?

Sanji worked at the Baratie floating restaurant. Sanji serves as sous chef at the Baratie, a ship-based eatery on the open sea that feeds travelers and those in need [ch. 912.5, p. 25]. The establishment requires cooks to cover dining duties in rotation because part-time waiters frequently abandon their posts [ch. 912.5, p. 25]. Zeff owns the Baratie and maintains strict kitchen standards while Sanji trains and prepares entrees there ch. 68, p. 10. Young Sanji practices dishes repeatedly inside the Baratie kitchen under Zeff's oversight [ch. 1054.5, p. 8]. "I'M THE SOUS CHEF OF THE FLOATING" [ch. 912.5, p. 25]. "TO BE HONEST, I'M NOT ACTUALLY A WAITER." [ch. 912.5, p. 24]. "I OWE A THING OR TWO TO THE OLD MAN THAT RUNS THIS PLACE." [ch. 912.5, p. 12]. The restaurant's floating design and demanding service shape Sanji's daily work alongside other chefs who argue over special orders [ch. 912.5, p. 11].
