If anyone likes this kind of free cooking style genre, then I recommend Hungry Heart Dinner game. The bgm, feels, conversations is almost the same style, a slight bit of patience is required, but no in-game purchases are required (unless u want it) The customers share their memories, some happy, some traumatic yet attempting to change, some may look normal on the surface but has a special place in their mind and so on. This manga was cute, although I couldn't completely comprehend their relationships, in short I felt that somewhere or the other that hiitokuchiya (written on the board at the entrance if you noticed, meaning "in one bite" if I recall Hito= people & kuchi= bite [referring to eating food in bites] and unique in itself) brought them all together, directly or indirectly. Thanks for the meal!
