leveling cooking is beneficial if you don't want to repeatedly buy food off the TP.
otherwise, yes, omnomberry bars are worth getting. ask guildmates first, though, because generally, the ingredients needed to make the bars are much less then buying them per unit. at times, i can even buy all the ingredients off the TP and make a profit just buying the raw ingredients and turning them into bars since you get 2 bars per craft.
