Some time ago I started reading a strange story in which there was a strange restaurant that was transforming people into desserts. Turning them with magic, not chopping them. There is some idol who is turn into a radish(?), that vegetable can walk and talk, but look nothing like human. You can eat for free. You can only be turn if you eat the special meal that goes with the golden ticket. The heroine is forced feed to eat that meal.

It was fully colored.

Hope you can help me find the title.

I found it after a lot of time. It is "A Taste of Temptation".
