I find it weird that someone would question you not drinking. If you were in a bar, well that's a somewhat normal question, but with dinner? I never drink and eat at the same time and no one has ever asked me why, how, who, what.
Your co-workers seem to be far too focused on alcohol- which is their choice but to try to drag you in to that is very rude and to ask you more than once or make a comment is rude.
I would say (nicely) - "I don't like alcohol - so I don't".
Bet they won't ask again. If they then asked "why" I would repeat, I don't like alcohol, so I don't. That should be the end of that line of questioning. If someone pursued it, I would just stop answering and read the menu. Just because someone decides to question you doesn't mean you ever have to participate.
