Hello, Using the verb "have" in its present tense form in such a sentence indicates a habit ,a regular behavior , so if you used that verb in this context the sentence could be for example: I usually have breakfast at 7am in the morning. But if you are having breakfast on a specific day at a specific hour you would rather use the present continuous : I am having breakfast with my friend in the club . ( This indicates that you are doing that at the moment ) .

I think this is what you mean. I have breakfast everyday.
