Main character gets transported to another fantasy world by a godess. He lives there for 9 years and finally succeeds in killing the demon lord and saving that world. The godess grants him and his companion a wish. Main character wants a restaurant in the real world where he can serve the dishes from this fantasy world, not because they are good but the food of this fantasy world is considered the worst in all realms. He wants others to go through the sane misery he went throught. The godess grants him his wish and he opens up his restaurant and starts getting some peculiar customers. 

This manhwa has a good mix of both cooking drama and hunter type action. The art of this manhwa is quite good and panels are well transitioned. This manhwa excels in the comedy department as well. Characters are written well with some uniqueness to them. Main character is overpowered from the start and he also has a decent personality. Worldbuilding can be a bit confusing for some readers because some things are left unexplained. Other than that it is a must try for everyone.
