First thing, don't read these books on an empty stomach; the descriptions and often the food picture given by the translator is sure to send you to your food ordering apps and lament if you can't order most of the dishes (because you don't stay in China). Anyway, the books here have food as the main ingredient of how the story progresses; some have FL and ML while some are BL. But lusting after food and drooling over dishes is common to all.
