"menyukai" is another form of "suka" with prefix and suffix me-i, in this sentence you could substitute suka with menyukai and both have the same meaning. the prefix 'me' is usually used to form an active verb, for example 'he drives a car' cant be translated as "dia kendara sebuah mobil", you have to add 'me-i' to 'kendara' and make it into "dia mengendarai sebuah mobil" to make the sentence correct, although in some cases, like this one, as far as i am aware, it has no difference.
