I don't think any of those sound very natural, really. We use the expression 'to have a soft spot' for people (and perhaps for animals, such as pets), but not for food, hobbies or other activities. i hope that helps!

I would advise students that this expression is used in conversational English to describe human interactions and relationships. Soft spot meaning one persons fondness for another person. Examples, "My father has a soft spot for his youngest grandson" "My daughter has a soft spot for a boy in her class"

Hi Apple, Yes - you can use the term in all of the above scenarios but from personal use/observation, I would say "soft spot" is normally used for somebody and normally by someone describing someone else (rather than themselves - but it is not a hard and fast rule). So "He has a soft spot for Apple" is a good example as someone talks to another about another! ;-) All the best Tom

US: It is usually used to describe a feeling about a person or group of people. It doesn't just mean fondness - it also means that the person is willing to make allowances and exceptions for (ignore rules) for the person(s). For example: "I normally do not let people into the store early, but I have a soft spot for Avengers fans and he was wearing a Hulk jacket." "My dad has such a soft spot for my brother. He's letting him go to the party without having finished his homework first."

As a native American English speaker, I agree that this is not natural usage. A 'soft spot' almost exclusively applies to relationship affections, pertaining to other people and pets. Now, you could use 'fond of' for describing items, but it still leans toward relationships. The best types of words for the above examples would be "I enjoy".
