be partial to (someone or something)

To be particularly fond of someone or something; to have someone or something as one's favorite or preference. I know Janet likes the cream color, but I'm partial to the robin's egg blue, myself. I'm always been partial to you, Tom, so I'm willing to give you the benefit of the doubt in this situation. You really like that big truck? I'm partial to the sedan—it would be so much easier to park.
