Seems to not be so good, not tested on melee jobs, tested on 75BLM
Margherita Pizza - 30HM 10% attack
Pepperoni Pizza - 30 HP +1STR 12% attack
Anchovy Pizza - 30HP +1DEX 10% attack
Attack could be capped, I don't know, was 10% on naked blm. Edit: Tested this on a friend 75PLD with Anchovy Pizza +1, his attack went up to 384 from 363, and he got +2 dex from the +1. So it looks like that 10% attack capped at +21 attack. I didn't test it for store TP, or any other stats.
Shrimp Sushi - 1VIT, 4% DEF, similar ACC/RACC as sole
Octopus Sushi - 1STR, similar acc/racc as sole.
Can't find Grauberg Lettuce, and some of the other ingredients to make the other food. Seems to not be worth the effort though for the pizza.
