This is quite interesting y’all! Please recommend more like this.

I'm not sure which you mean, but I'll be starting off with manhwa's where the MC is a cook + fantasy that I can list at the top of my head;

• Bizarre Restaurant / Overeating Restaurant
- MC can give buff using food/cooking, Hero/Returnee MC, Dungeon, Monsters, Hunters

• Become A Kitchen Soldier Legend / Kitchen Soldier
- Soldier & Cook MC, System/Ability related to cooking, Non-Apocalyptic

• The Archmage's Restaurant
- MC becoming a cook/owning a restaurant after retirement, MC transmigrated to another world, Mages, Dragons, Knights, Elves, Royals

+ where it's the start of the Apocalypse/Monster Invasion but the MC isn't a cook or the story isn't related to food

• Hiding a Logistics Center in the Apocalypse
- it's just as the title says, System, MC found a loop(?) in the system, start of the Apocalypse
• The Ultimate Shut-in
- MC has OP ability, start of the apocalypse, System

PS. I know there's more of them, but I can't bring myself to look into my reading list (￣∇￣") maybe I'll add more if I come across them! I hope this will do for now

Thank you! I know and enjoyed reading Logistics Center and Ultimate Shut-in. I will check out the others that you mentioned. Thank you!
