A: Where are you going?
B: I am going to the/a gym. (first time ever B has mentioned the 'gym' to A)
My intuition tells me that I should use 'the'. But the 'gym' is an new information for A. So should it be 'a gym' or 'the gym' in the conversation?

Unfortunately, in English there are many exceptions to the so-called rules.
Usually we use the definite article to indicate a specific instance of the type of thing we're describing:
I ate the apple that you were saving.
Sometimes, we use the definite article to mean the exact opposite, that is, an unspecified instance of the type of thing described:
Ex:
I took a walk in the woods - the woods does not designate a specific area, but actually refers to a wooded area whose location is not pertinent
I have to stop at the store on my way home - the store really means any old store, it doesn't matter which.
Every Friday, I go to the cinema - Which cinema? Any cinema.
Whenever I'm at the beach, I build a sandcastle - The speaker would not mean "whenever I'm at this one specific beach I build a sandcastle," but instead "any time I'm at any beach, I build a sandcastle."
I try to go to the gym every day of the week. I go to a gym near my office during the week, and one near my house on the weekend - Here the gym clearly cannot refer to a specific gym, because two different locations are mentioned.
All of these examples use the definite article, but they describe a generic location, or a generic activity. "Going to the gym" can sometimes mean moving your body through space such that you transport yourself to a specific building, which is a specific gym. But just as often (or perhaps more often) it means working out at some unspecified gym.
The real trouble is, some generic locations/activities use the definite article and some use no article, e.g. I'm going to school, I'm going to work, I'm going home, I go to university, I'm going to practice, etc.
How do you know which is which? Memorization.
Interesting question, and so much is dependent on usage.
For example, on might say either
I'm looking for a restroom.
I'm looking for the restroom.
but specifically would only say
I'm looking for the Gents. (BrE)
In the normal course of conversation, A would say to B
I'm going to the gym.
since (s)he is habitually going to a specific place, whether or not already known by B.
Whereas, if A was looking for a gym to join, (s)he would say
I'm going to go look for a gym to join.
(a specifc gym has not been determined)
but if (s)he was looking for a specific gym to meet friends
I'm going to look for the gym where we are meeting.
(a specific gym has already been determined)
Sometimes use of a vs the is not determined by specificity
P1: "You have a phone message from this morning."
P2: "What is the message?"
In this example, the "a" in the first line refers to the number of messages, and the "the" in the second line refers to the specific message.
Whether the information is "new" or "old" to the listener doesn't trump other considerations. It is just one of the many contexts that can cause speakers to choose the definite article over the indefinite article, or vice versa.
Going to the gym can simply be a way of referring to the familiar activity of exercising at a place devoted to exercise. It need not refer to a particular place, though it can.
A person who started going to the gym when they got their first job three years earlier, a job which has required them to relocate to five different cities in that space of three years, might say:
I've been going to the gym for three years.
even though five different gyms are involved. The reference is to the familiar activity.
I am going to the gym. Is correct in my opinion because "the" Is a definite article. "The gym" Means particular gym you go. Where as "a gym" Does not define to which gym you are going.
In general “the” implies a specific noun or something that is the only one in a specific place. Like you might say,
Excuse me, I’m looking for the restroom
in a restaurant where you only expect there to be one, or you might say,
Excuse me, I’m looking for a restroom
in an airport where you expect there to be more than one.
Anyways, in this context, “the” just implies a specific gym they are talking about, therefore “the” is more appropriate. But “a” could also be used if there are more than one in the area this conversation is taking place.
