Not your cup of tea

Example 1:
Harold: Hey Dirk, do you want to go get some sushi later?
Dirk: No, that’s okay. Sushi is not my cup of tea. I would prefer some barbecue.

Example 2:
Julie: Hey Pam, have you ever been to New York?
Pam: Yeah, but I didn’t really like it.
Julie: Really? Why?
Pam: It was very busy and fast. It’s just not my cup of tea. I like Los Angeles because it’s relaxed.

Example 3:
Rob: Does your girlfriend like ice-cream?
Wes: No, it’s not really her cup of tea. She only eats it once in a while. She likes cake more than anything

Explanation: To say something is “not one’s cup of tea” is to say that a person doesn’t like something or it is not their favorite. If something is not your cup of tea, it is not your preference, but it might be an acceptable choice.
