Learn Swedish: Hon tycker om antikaffären som vi brukar besöka. - She likes the antique shop that we usually visit.

In English, we often drop the word "that" when it is the object of the relative clause (e.g., "the shop we visit"). In Swedish, you are allowed to drop som when it acts as the object, so antikaffären vi brukar besöka is grammatically correct. However, keeping som is very common and often makes the sentence flow better, so it is a great habit to leave it in.

Why does the sentence use tycker om instead of just tycker or gillar?

Tycker by itself means "thinks" in the sense of having an opinion. To mean "likes", you must add the little word om. You could absolutely use gillar here instead (Hon gillar antikaffären), and it would mean the exact same thing.

Where is the word for "usually" in this sentence?

Swedish uses a specific verb for doing something habitually: brukar. It works like a helping verb and translates to "usually do" or "to be in the habit of". Because it is a helping verb, it is followed directly by the infinitive form of the main verb, which is why we use besöka (to visit) right after it.
