Temple bar is great in the way that, yes it is a tourist trap, but you will meet people from many different places because of that fact.
It is big inside with multiple rooms and commercialized music playing (expect Ed Sheeran).
I went here a few times with people from all over at my hotel (France, Austria, West Coast USA) and had a great time.

If you want to check out bars with more authentic Irish to them, check out the back page in northern Dublin or the brazen head. I do recommend you at least pop into temple bar to experience it though.
