Heehee's feed

Can't remember what it's called.
Main traits:
- Fantasy shounen manhwa
- Protag returned from other world
- Protag opens restaurant/diner/cafe
- There are now gates and hunters in his world
- Has a pet from other world that is good at housekeeping
- This kind of pet in other world is too good at their job and supposedly made other heroes in other world lazy
- Cooks bad tasting food with monster meat that supposedly helps with training

Thanks in advance
