Original title 폭군의 셰프 (The Tyrant’s Chef). Kind of a ridiculous mashup of rom-com, Joseon court intrigue costume drama, time-travel fish-out-of-water, and workplace sitcom, but there are a good number of fun cooking and serving scenes.
One particularly ridiculous bit: the action starts with the chef character winning a French cooking competition in which the prize is being made chef of a three-Michelin-star restaurant.
