What Does IF SO Mean?

If it is so -/ If it is true that you like talking about the weather, etc.

mooyongI guess that mean if you like

This is a different idiom, which I don't think is what you mean.
"I can help you across the street, if you like."

mooyongDo you like talking about the weather? If so, you should really try ...

= Do you like talking about the weather? If you like talking about the weather, you should really try ...

Compare:

Are you looking for a good place to eat? If so, try John's Excellent Restaurant on Elm Street.
=
Are you looking for a good place to eat? If you are looking for a good place to eat, try John's Excellent Restaurant on Elm Street.

so takes the place of the whole preceding idea.

Hi,
I would like to know what does "if so" in this sentense mean

Do you like talking about the weather?
If so, = If you like talking about the weather,
you should really try the English test in today's lesson because it contains a lot of useful weather expressions. What's more, Alan has written this test in the form of a real mini-weather forecast.

I guess that mean if you like

Somebody know please explain me.
